How do you find the square root of sumthing? What IS the square root? Help Me please!!!!?

Answer 1

The square root of X = X raised to the 0.5 power. Aside from 0, all numbers have two square roots. For example, the square roots of 4 are 2 AND -2.

Answer 2

In math, we talk about operations and inverse operations. So if we take a number (like 7) and multiply by iteself, we have "squared the number" and have 49. The inverse operation is if we have 49, what two numbers multiplied by each other will yield 49 as a product. Here 7 is the SQUARE ROOT.

You can find the square root though a modified-division procedure which is really based on quadratic equations. The specific equation is
(a + b)^2 = ? given a and b. The answer is a^2+2ab+b^2. In the procedure, we "close" in on a value for a (an approximation to the square root) while making b very small compared to a. Then (a+b)^2 almost equals a^2+2ab.

Answer 3

The value of a square root of a number is that number raised to the power of 1/2.

Just as the cubed root is the number raised to the power of 1/3 etc.

The square root allows us to write powers without fractions.

Answer 4

Square root of something is a number times itself equals the square. For example

square root 4 is 2

Why? Because 2 X 2 = 4

square root 16 is 4

Why? Because 4 X 4 = 16

It's the same number times it's self, but you do it backwards. there's a square root button on a calculator to help

Answer 5

it is the number that, when multiplied times itself, renders that number it is the square root of.
