### What is the square root of 81?

Hello,

When asking this question, remember that the answer will always be positive and negative.

The square root of 819 and 9 for this problem is because:

9 x 9 = 81 =)

Yes

9 x 9 = 81 = D (If you multiply two negative numbers, you get a positive number)

9 and 9.

## What Is The Square Root Of 81

The square root of 81.

It's actually a little difficult ...

9 * 9 = 81.

9 * 9 = 81.

So 9 and 9 are equal to 81 squares. The problem is that mathematicians want the square root to be the mapping of a real number (or a complex number, in order), which means that. One action or another Somehow formally, huh.

f (x) = square (x)

f (81) = one.

f (81) = b

So a = b, otherwise f is not really a process. Therefore, we cannot put f (81) = 9 and f (81) = 9.

(If the square root has no function, then it's a complete mess, coordinates and receives functions, not artificial equations, then you can't calculate the square root)

We solve this by explaining the function of a square root to get a positive square root. So there are two numbers that you can square to get 81, but generally you would say that the square root of 819 is the square of 81, just to indicate the number you want. Connect the positive and negative squares

Is this too much information?

Âš81 = 9.

Finding the square root of a number is the opposite of finding the square of a number. Remember that the square of a number is a number that multiplies by itself.

9x9 = 81.

So the square root of 81 is 9.
