Can someone help me please!!

Answer:
"B" is the correct answer.
Step-by-step explanation:
First, lets simplify the second term: 2^-7. This simplifies to 1/2^7.
Second, lets evaluate: 2^4 = 16 and 1/2^7 is 1/128.
Finally, lets completely evaluate. 16 times 1/128 is 0.125. And, that is equivalent to 1/2^3.
