If n is a positive integer, is the value of b – a at least twice the value of 3n – 2n?
(1) a = 2n + 1 and b = 3n+1
(2) n = 3
Any decimal that has only a finite number of nonzero digits is a terminating decimal. For example, 24, 0.82, and 5.096 are three terminating decimals. If r and s are positive integers and the ratio r/s is expressed as a decimal, is r/s a terminating decimal?
(1) 90 < r < 100
(2) s = 4
