Answer:
[tex]-7^2 + 5^4[/tex]
Step-by-step explanation:
Essentially, you are seeing how much of each of the same term there is. Add the amount together, and it will be the exponent.
[tex](-7) * (-7) = -7^(1 + 1) = -7^2\\5 * 5 * 5 * 5 = 5^(1 + 1 + 1 + 1) = 5^4[/tex]
Combine the two terms together into an expression. Note that you cannot combine them.
[tex]-7^2 + 5^4[/tex] is your answer.
