Could somebody please explain how to simplify this expression?
Write your answer without using negative exponents.
Assume that all variables are positive real numbers.
Thank you in advance.
Recall that when you raise a variable to a negative exponent like this:
You can change the sign of the exponent by dividing the variable into 1. So:
Using this rule, we can say that:
Recall the rule of exponents that says:
So we can simplify our expression to:
Simplify the fractions:
And recall that
So your final expression is:
