Which expression is equivalent to 2^4 ⋅ 2^−7?

the answer for this is:

subtract 7 from 4 to get -3

 you then have 2^-3

remove the negative exponent by rewriting as 1/(2^3)

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
