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

x - sqrt(x) = 0\nx = sqrt(x)\nx^2 = x\nx(x-1) = 0\nx = 0,1\n\nBoth check.

The answer is zero isn't it?  The square root of (7 squared) is 7.  If you minus 14 you get -7. Add another 7, brings you up to zero.

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

The "principal" square root is the positive one, 4/5.\n\nThe "negative" square root of the fraction is -4/5, because\n\n-4/5 * -4/5 = 16/25 also.

Renee, do you know what a square root is? It's a number, which, when multiplied by itself, gives the original number. So the square root of 900 is 30, because 30 * 30 = 900. That is called the "principal" square root.\n\n900 also has a negative square root, -30, because\n\n-30 * -30 = 900 also.

sqrt(157452304)= +/-12548\n\ndon't forget that 2 negatives cancel out so every number has 2 square roots (either rational or irrational) , one positive and one negative.

Before you can compute a logarithm, you have to define a base that we can call b, where b > 0.  If the log base b of a number x is equal to k, then that means that x = b^k.  Since b is positive, then x has to be positive.\n\nIf a = sqrt(b), then that means that a*a = b.  If a is positive, then a*a is a positive times a positive which is positive.  If a is negative, then a*a is a negative times a negative which is positive.  Thus for the square root function to make sense, then b must be positive.

Because -2 squared = (-2)(-2)\n\nA negative times a negative equals a positive.

I think you mean find the cube root of -8/27:\n\nCube root of a negative is negative.\nCube root of 8 is 2\nCube root of 27 is 3\n\nSo the answer is -2/3

just remember that i equals the square root of -1.  every time you see a negative square root split it up:  square root of -16 = sqare root of 16i = 4i.\n\nif you have 4i x 5i, then you multiply and get 20i^2 and since i is the square root of -1, i^2 = -1.  so 4i x 5i = -20.\n\nhope that helped a bit...

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).

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.

the answer is - 16\n\nsince you have one negative, it is a negative answer
