you wright the fraction
2^3 /2^4 then you expand the powers out then you cancel all the identical items on the top and botttom then your answer will be 2

we expand the exponents  and get
2.2.2.2 x 2.2.2
then we get 2 and add the 4+3 that would be 7 so it would be 2^7 then you multiply 2.2.2.2.2.2.2 7 times and that would be = 128
