Answer = B

Explanation :

The expression (the answer) is equal to 4^5 times 4^-7 divided by 4^-2

Expression = 4^5 x 4^-7 divided by 4^-2

Since the base for all terms are the same(all bases are 4)
All we have to do is add and subtract the exponents accordingly

4^5 x 4^-7 = 4^-2

Now what’s left of the equation is 4^-2 divided by 4^-2
When you divide any number by itself (except 0) you always get 1 as the asnwer

4^-2 divided by 4^-2 = 1

Answer choice B = 4^0 (4^0 equal 1, when a number has an exponent of 0 the answer will be 1)

Answer = B
