Question

Simplify ((–3)^2)^3.

Answer 1

(-3)^2= 9

(9)^3= 729

Hence ((-3)^2)^3 =729

Answer 2

Just work out yourself from every parentheses.

We have the expression ((-3)^2)^3

Inside the first parentheses, we have (-3)^2
Solve that.

(-3)^2 = (-3)(-3) = 9

Now we will have 9^3
Which is 9 * 9 * 9

9 * 9 * 9 = 729

So, 729 is the answer.
