## Does squaring a square root cancel it?

We can say that the square root and the square cancel each other out. They are the inverse of each other. If we have a number written with the index 2 ( squared ) then taking the square root simply means that we leave out the 2 ( this only applies to positive numbers ).

## Why is 9 The square root of 81?

Explanation: 81 = 9 ⋅ 9 then the square root of √ 81 = 9. Because the double multiplication for the same sign is always positive, the square root is also valid with the other sign 81 =(− 9 )⋅(− 9 ) then √ 81 =− 9 and we can say that √ 81 =± 9.
