Find the number of different ways in which 7^11 can be expressed as the product of three factors Choose the correct choice from the following options:
A) 13
B) 14
C) 15
D) 16
E) 17
let 7^11=7^x*7^y*7^z   then possible triplets of (x,y,z)   (0,0,11)(0,1,10)(0,2,9)(0,3,8)(0,4,7)(0,5,6)   (1,1,9)(1,2,8)(1,3,7)(1,4,6)(1,5,5)   (2,2,7)(2,3,6)(2,4,5)   (3,3,5)(3,4,4)   so number of different ways=16   ANSWER:16
