When there is a multiplication involving exponents, we need to evaluate the numbers and each variables separately. In this case, we have 5 and 4 as the numbers, and w and h for the variables.
When we multiply 5 and 4 we get:
For w, we have
, 
, 
. While we are multiplying the w's, we need to add the exponents together to get the final answer: 
For h's, there are
, 
, 
. When we apply the same thing to h's, we get 
For the final step, we need to write all of these together:
