If k is an integer greater than 1, is k equal to 2^r for some positive integer r? (1) k is divisible by 2^6 (2) k is not divisible by any odd integer greater than 1




a) k can be defined as multiple of 2^6. So it can also conatin an odd factor(i.e. k = 2^6*3,2^6*5... ) which will make this stmt Insuff.

b) K cannot conatin any odd factors....i.e. the factors can be expressed in the form of 2^r. Suff
