You should use order of operations to simplify the equation. Here's the math:
Let's work on one equation at a time, first this one:
Distribute the exponent (³) to all the terms within the parentheses:
Remember to multiply the exponents for variables. Now, simplify the terms:
Distribute
to all the terms in parentheses:
Now, let's work on the second expression:
First, distribute the exponent
to the terms in parentheses:
Simplify by multiplying the exponents:
Now, we can find the quotient of the two expressions:
Separate the
terms in the denominator into factors that go into the numerator:
Divide:
