Question

Which radical expression is equivalent to k^2/9. Please give me a step-by-step explanation.

Answer 1

Let's simplify

`\\ \rm\Rrightarrow (k^2)/(9)`

`\\ \rm\Rrightarrow (k^2)/(3^2)`

`\\ \rm\Rrightarrow ((k)/(3))^2`

Answer 2

Apply the rule x^m/n = n√ x^m to rewrite the exponentiation as a radical.

9√k^2
