Answer 1

Answer: $4^0$

Step-by-step explanation:

$4^5*4^-^7/4^-^2$

Rewriting this;

$\frac{4^5*4^-^7}{4^-^2}$

When you multiply by the same base, you add exponents.

$\frac{4^5^+^(^-^7^)}{4^-^2}$

$\frac{4^5^-^7}{4^-^2}$

$\frac{4^-^2}{4^-^2}$

When you divide by the same base, you subtract exponents.

$4^-^2^-^(^-^2^)$

$4^-^2^+^2\\4^0$
