Exercise 57 Page P21

If $n$ is an odd number, then the radical expression $n a^{n}$ simplifies to $a .$ If $n$ is even, the expression $n a^{n}$ simplifies to $∣ a ∣ .$

$\frac{x 2 1 x}{3}$

Practice makes perfect

For any real number

a,

the radical expression

n a^{n}

can be simplified as follows.

n a^{n} = {a if n is odd ∣ a ∣ if n is even

In this case, the index number of the expression is even so the expression underneath the radical is positive.
