No exponents are needed. The prime factorization is: 5 x 11
11 is a prime number in its own right and needs no exponents
99 = 32*11
It is: 72*11 = 539
11 x 17 = 187 No exponents necessary.
5 x 11 = 55 (no exponents are needed).
11 x 17 = 187 (no exponents needed).
As a product of its prime factors: 3*5*11 = 165 none of which have exponents
528 = 24 * 3 * 11
It is: 22*52*11 = 1100
44 = 22*11
32 x 11 = 99
