2i. The character "i" denotes the square root of -1, which is not a real number. So, the sq. root of -4 is 2i.

This seems to be a popular question. There is no real number that is the square root of -1.  However, it turns out that it is useful to develop as set of numbers that allows the square root of -1.    This is called "i" as is known as an imaginary number.  The set of numbers that includes i is called the set of complex numbers.

I think it is \nf(s)=√(pi/s)\n\nBy the way how do you do the sign for the sqrt?\nI still cant figure it out.\nI can do it in MS Word but when I copy into the the Firefox I get anything, but what I desire.\n\nIt is getting late, very late\n\nI'm running 2000. \nThank you Scott\nand \nnwohiosteve  thank you for the hint. My memory is refreshed.\npress ALT, ASCII  number , reliese ALT works

The square root of a negative number is an imaginary one.  The square root of -1 is known as i.  Negative square roots work out like positive ones, only with the i, so SqRoot(-4) = 2i and SqRoot(-64) = 8i.

It depends on what numbers r, e, and d stand for.  For example, if r=2, e=1, and d=8 then red = 16 and its (principal) square root would be four.

Mathematicians have designated a special number 'i' which is equal to the square root of minus 1. Then, it follows that i2 = -1. To determine the square root of a negative number (-16 for example), take the square root of the absolute value of the number (square root of 16 = 4) and then multiply it by 'i'. So, the square root of -16 is 4i.\nAs a double check, we can square 4i (4*4 = 16 and i*i =-1), producing -16.\nAll negative square roots are called "imaginary numbers" (now you know where that letter 'i' comes from).

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 a number is a number which, when multipled by itself, gives the original number. The square root of 16 is 4; the square root of 25 is 5. The square root of 1 is 1.\n\nSome numbers have no exact square root. The square root of 20 is somewhere between 4 and 5, but no sequence of digits, no matter how long, can produce an exact value which, when multipled by itself, will give 20. The square root of 20 is called an "irrational" number. We can know that the square root of 20 is twice the square root of 5, but the square root of 5 is irrational, also.\n\nIf you want to know how I know that the square root of 20 is twice the square root of 5, pick this answer as best and ask another question ("How do we know that the square root of 20 is twice the square root of 5?").

The easiest way to find a square root is to use a calculator, but you can do it without one. Here’s one way, using 12 as an example of the squared number:\n\n   1. Pick a number that when squared, comes close to (but is less than) the number whose square root you’re finding: 3 × 3 = 9. This is a better choice than 4: 4 × 4 = 16\n   2. Divide the number you’re finding the square root of (12) by the number you squared (3) in step 1: 12 ÷ 3 = 4\n   3. Average the closest square root (3) and the answer of step 2 (4): 3 + 4 = 7. 7 ÷ 2 = 3.5\n   4. Square the average to see how close the number is to 12:\n\n3.5 × 3.5 = 12.25—Close, but not close enough!\n\nRepeat steps 2 and 3 until the number squared is very close to 12:\n\nDivide: 12 ÷ 3.5 = 3.43\n\nAverage: 3.5 + 3.43 = 6.935\n\n6.935 ÷ 2 = 3.465\n\n3.465 × 3.465 = 12.006, close enough!

The problem is that there are two possible square roots for each complex number other than 0. You can't consistently pick one for each complex number and keep the property that the square root of a product is the product of the square roots. In your example, both 1 and -1 are square roots of 1 and your calcualtion shifts from one to the other.

well, a square root function looks like...half of a bridge or an arc. it starts at (0,0) and gradually rises for infinity. there's your basic shape.  now i am not exactly sure on your equation, but if the +3 is INSIDE the squareroot, then you would shift the graph to the LEFT 3. (yes, the opposite) but if it is OUTSIDE the squareroot, then you would shift it UP 3.

sq.rt of x*y = Sq.rt X * sq.rt. Y\n\nIt can be proven that:\n √(x*y) = √x * √y\n\nConsider the first part → √(x*y).\nTwo number values, one is x and the other is y, they are multiplied together.  You then take the square root of this result.\n\nConsider the second part → √x * √y.\nYou take the square root of x and y and then you multiply the results together.\nIt can be shown that the results of the first part is the same as the result of the second part.
