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:
[tex]5 \times 4 = 20[/tex]
For w, we have [tex] {w}^{6} [/tex], [tex] {w}^{4} [/tex], [tex]w[/tex]. While we are multiplying the w's, we need to add the exponents together to get the final answer: [tex] {w}^{6} \times {w}^{4} \times w = {w}^{11} [/tex]
For h's, there are [tex] {h}^{2} [/tex], [tex] {h}^{5} [/tex], [tex] {h}^{4} [/tex]. When we apply the same thing to h's, we get [tex] {h}^{2} \times {h}^{5} \times {h}^{4} = {h}^{11} [/tex]
For the final step, we need to write all of these together: [tex]20 \times {w}^{11} \times {h}^{11} \: \: or \: \: 20 {w}^{11} {h}^{11} \: \: or \: \: 20 {(wh)}^{11} [/tex]
