Answer: [tex]4^0[/tex]
Step-by-step explanation:
[tex]4^5*4^-^7/4^-^2[/tex]
Rewriting this;
[tex]\frac{4^5*4^-^7}{4^-^2}[/tex]
When you multiply by the same base, you add exponents.
[tex]\frac{4^5^+^(^-^7^)}{4^-^2}[/tex]
[tex]\frac{4^5^-^7}{4^-^2}[/tex]
[tex]\frac{4^-^2}{4^-^2}[/tex]
When you divide by the same base, you subtract exponents.
[tex]4^-^2^-^(^-^2^)[/tex]
[tex]4^-^2^+^2\\4^0[/tex]
