Answer 1

`13^(3)`

Explanation:

The multiplication exponent laws states that when two numbers with the same base are multiplied together, the exponents will add together, so:

`x^(a)*x^(b) =x^(a+b)`

Let's rewrite the question in this format:

`13^(2) *13^(-4) *13^(5) =13^(?)`

This is equal to:

`13^(2) *13^(-4) *13^(5) =13^(2-4+5)`

2-4+5=3

Therefore the answer is
`13^(3)`.

Hope this helped!
