Question

How do you simplify square root of 17 times the square root of 17 to the 2nd power?

Answer 1

The question is ambiguous, but could be answered:

(1) `sqrt(17)(sqrt(17))^2 = 17sqrt(17)`
(2) `(sqrt(17)sqrt(17))^2 = 17^2 = 289`

Explanation:

In general `(sqrt(a))^2 = sqrt(a)sqrt(a) = a`

A square root of a number is a number which when multiplied by itself gives the original number.
