Finding the suare root of -ve number involves using imaginary number 'i'.The value of i is taken as (-1)^(1/2).\nThat is, i=(-1)^(1/2).\nNow, suppose you want to find sq. root of -25.\n-25=25*(-1)\nTaking sq. root on both sides we get\n(-25)^(1/2)=25^(1/2)*i   {since (-1)^(1/2)=i}\nTherefore root of -25 is 5i.\nAlthough, we have found root for -25 this method is general and can be applied for any negative number.

1) Evaluate 3 square root of -8 , if possible:\n-2\nbecause (-2)(-2)(-2)=(4)(-2)=8\n\ncareful, the answer of Gistamb... is wrong!\n\n2)simplify the square root of 180\n\nsqrt(180)=\nsqrt(18*10)=\nsqrt(9*2*5*2)=\nsqrt(2*2*3*3*5)=\n2*3sqrt(5)=\n6sqrt(5)\n\n3)simplify the square root of 7/100\n\nsqrt(7/100)=\nsqrt(7)/sqrt(100)=\n(sqrt(7))/10

Unfortunately there is not. There is however an algorithm that will allow you to work out square roots by hand.

The answer, before simplification, is sqrt(-8). There is no need to panic, as some of the other answerers did. This simplifies easily to\n\n2 * i * sqrt(2)

idk wat the square root is.... the square root of a negative is not a negative though... a negative times a negative is a positive.... also, this is the 4th ? i have answered of urs

did you mean the square root of x-1 = 3?\nin that case it will be 2:\nadd positive 1 to both sides:\n   x-1+1= 3+1\nthen solve the remaining equation:\n   x=4\nget the square root of 4:\n   x=2

Square root of four has two solutions: 2 and -2.\n2 is a natural number. All natural numbers are integers. All integers are rational.\n-2 is NOT a natural number (no natural number is negative). But it is an integer, so it's a rational number.\nAs rational numbers are opposed to irrational numbers, none of the two solutions can be irrational.

The Babylonian method is easy and fast:\n\nn[i+1] = (n + (r/n))/2\nwhere n is the approximate root, and r is the number you wish to find the sqaure root of. Check sources for more info.

the square root of -1 is assigned the symbol i.\n\ni^2 = -1.\n\n A complex number is of the form a + bi (where i has meaning) and a and b are real numbers.
