what is square root? how do you square root a number?

When we square a number we multiply it by itself\n\nThe square root of a number is the number that when multiplied by itself makes that number.\n\nFor example:\n\nThe square root of 9 is 3 (3 * 3 = 9)\n\nThere are different ways of finding the square rot of a number (by hand - using a calculator is just too easy lol) and the source below shows you some of them.

For numbers greater than one, the square root of the number is less than the original number. (e.g. square root of 9 is 3.)\nBut for numbers between zero and one, it is the other way around. \n\nThink of it this way. When you square a number larger than one, e.g. 3*3 = 9, the result is bigger. When you square a number between zero and one, e.g. 1/2 * 1/2 = 1/4, the result is smaller. \n\nTaking the square root is like undoing the squaring operation. So when you take the square root of a number larger than one, the result is smaller than the original number. (e.g. square root of 9 is 3). And when you take the square root of a number between zero and one, the result is bigger than the original number. (e.g. square root of 1/4 is 1/2.)

The square root of 1 is 1.\nsqrt(6.6) = 2.569\nsqrt(15) = 3.873

first of all you have to know all your square roots I will give you the first 12: besides 1, 4,9,16,25,36,49,64,81,100,121,144 then from Ill tell ya square root of 48, you see dat 4 will go into 48 so write square root of 4 and square root of 12 then you have 2/ square root of 12 then you see 4 can go into square root of 12 so then put square root of 4 and square root of 3 then you will have 2 so multiply the 2 times the other 2 and you will have 4/square root of 3 and that's your answer I wish I could show it to you, it would be better to understand but hope this helps.

Just as the reciprocal of the number 2 is 1/2, or 0.5, the reciprocal of the square root of 2 is the square root of 1/2.  This is represented numerically as 0.707106781186...  Try it again, this time using numbers which will yield whole-number results.  For example, take the number 64.  The reciprocal of 64 is 1/64 or 0.015625.  The square root of 64 is 8, and the reciprocal of 8 is 1/8 or 0.125.  Note that the square root of 0.015625 is 0.125.

Always remember:\n"The Product of square roots of 2 numbers is equal to the square root of their product"\nIn symbols, \n(√a)(√b) = √(ab) and\n√(ab) = (√a)(√b)\nso,\n2√12 = 2√(4*3)\nUsing our 'Property',\n2√12 = 2(√4)(√3) but √4 = 2, so\n2√12 = 2(2)(√3)\n2√12 = 4√3\n\nHope this helps^_^

since there is no real answer to the square root of any negative number we write i\ni=the square root of -1\n\nif you did the square root of -25 you would get 5i which equals to 5 times the square root of -1

The answer that others have offered (that the square root of infinity is infinity) is not really helpful, I think.  The problem is that infinity is not a number, but a direction, like "east," or to use a more mathematical term, like "less." It makes no sense to ask for the square root of infinity (or how big is "infinity plus one," or anything else that that treats infinity as a specific number). \n\nJust to confuse things a little, however, there is such a thing as "degrees of infinity."  ;-)

Can you use a square root symbol?  If so, sqrt(9) + 9 - 9

If you start with a number bigger than one, then the square root will always be smaller than the number, but bigger than 1.  So every time you take the square root, the number gets smaller, but never gets smaller than one.  Eventually it's so close to one that the calculator just displays it as 1.

The square root of -1 cannot be a real number, because there's no number which, when multiplied by itself, gives -1.  So the square root of any negative number cannot be a real number, because for any number -n, it is equal to -1 x n.  You can take the square root of the positive n, but not the -1.  We call the square root of negative one by the letter "i", standing for "imaginary".  The square root of -16 would be +/-4i.  Zero is a real number, because it denotes the number of things when there aren't any, and it is a placeholder for the origin of a real line.  Negative numbers are also real numbers, as used on a number line, or as a measure of the balance in your bank account if you go into your line of credit.

You figure the square root of each number separately...you've probably learned that in class alredy (how to do that)...then you take reach result, and multiply them together for your final answer.\n\nUse your textbook for reference...good luck!

no,12 has no perfect square root.it is an irrational number.but approxmiately the answer is 3.46....

In mathematics, the cube root ( ) of a number, x, is the number which, when multiplied by itself and then multiplied by itself again gives x. For example, the cube root of 8 is 2, because 2 × 2 × 2 = 8. In general though, a real number has three cube roots, one real number, and two complex numbers. \nThe cube root operation is associative with exponentiation and distributive with multiplication and division, but is not associative or distributive with addition or subtraction.\n\nFigure it out!\n\nGood Luck!

The square root of Pi lies between 1.75 and \n1.78125. We can get finer and finer bounds for \nthe value of the sqaure root of Pi.  After a while we will see that the square root of Pi equals 1.77245....  Since Pi is irrational we can never get an exact answer and we have to settle for an approximation.

That just means that keep it in the square root instead of simplifying it.\nEx: Keep it as square root of 2 instead of 1.414\n\nSo if you're finding the square root of 27, for example.  You can split up 27 into 9*3.  Square root of 9 is 3, but 3 is not a perfect square.  So your answer would be : 3 square root of 3.  Instead of 5.196

sqrt() means square root of:\n\n18)\n\nsqrt (3yx)/x\n\nI got that by multiplying both top and bottom by sqrt(x)\n\n\n19)\n11*sqrt(3)/3\ndid the same thing\n\n20) sqrt (6) divided by 3\nsame thing
