Question

Simplify: 9 squared to the 2 power

Answer 1

The given expression is

`(\sqrt[]{9)}^2`

The first step is to evaluate the term in the bracket. The suare root of 9 is 3

`\sqrt[]{9\text{ }}=\text{ 3}`

Then we would square the result

`3^2\text{ = 9}`

The answer is 9

It could have been done this way

`(9^{(1)/(2)})^2=9^{(2)/(2)}=\text{ 9}`
