Question

Help simplify this expression I am having a hard time please explain how you got your answer 5/b-3

Answer 1

Given:

`\text{ }(5)/(b^(-2))`

Recall the following rule: The negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa.

Since b^-2 is in the denominator, we will now be putting it into the denominator and remove the negative sign.

We get,

`\text{ }(5)/(b^(-2))=(5b^2)/(1)=5b^2`

The answer is:

`5b^2`
