Answer:

A, B, C,

Step-by-step explanation:

Just use a calculator...?

$2^-^2*2^8=\frac{1}{2^2}*2^8=\frac{2^8}{2^2}=2^8^-^6=2^6=64\\$

$3^-^5*3^1=\frac{1}{3^5}*3=\frac{3}{243}=\frac{1}{81}$

$4^4*4^-^3=\frac{4^4}{4^3}=4^1=4$

$5^3*5^-^1=\frac{5^3}{5^1}=5^2=25$

$6^-^8*6^-^6=\frac{6^6}{6^8}=6^-^2=\frac{1}{6^2}=\frac{1}{36}$

$8^2*8^-^4=\frac{8^2}{8^4}=8^-^2=\frac{1}{8^2}=\frac{1}{64}$
