Question

Anyone know what the answer is???(sorry if it’s unclear)

Answer 1

The laws of exponents I will be using are:

`(x^y)^z = x^(yz)`, and
`x^y \cdot x^z = x^(y+z)`.

For the first part,
`(15^3)^3 \cdot 15^(-6) = 15^9 \cdot 15^(-6) = 15^3`.

For the second part,
`15 \cdot (15^3)^2 \cdot (15^(-5))^2 = 15 \cdot (15^6) \cdot (15^(-10)) = 15^(1+6-10) = 15^(-3) = (1)/(15^3)`.
