Answer:
7³*5⁴
Explanation:
First, we had to put these in exponential form. We had 7 multiplied by itself 3 times, so we put a superscript of three. We also had to multiply 5 by istlef four times, so we put a superscript of four above the five. Next, we know they are being multiplyed together, so we have the two numbers, now in exponential form, and we put the multiplication symbol between them.
