Now, we know through the distributive property that we can distribute the to everything in the parenthesis. Once this is done, we get:
Now, we know through the power rule that when two exponents are multiplied together with the same base, the exponent can be added together . This then would make our equation:
Giving us for our final answer:
Hope this helps!
