Hey guys, need some brushing up on my work with exponents. Ran across these questions on a practice test and could use some help. Thanks in advance.
1) (10^8 - 10^2) / (10^7 - 10^3) is closest to which of the following?
a) 1
b) 10
c) 10^2
d) 10^3
e) 10^4
2) If (2^x)(3^y) = 288, where x and y are positive integers, then (2^x-1)(3^y-2) equals which of the following?
a) 16
b) 24
c) 48
d) 96
e) 144
