2 x 32 x 5 = 90
As a product of its prime factors in exponents: 3^3 times 11^1 = 297
2 x 29 = 58 (no exponents needed).
12 2X6 2X2X3 22X31
No, none of the factors are repeated.
78 = 2 x 3 x 13 None of its prime factors is repeated, so there's no application for exponents.
22*72 = 196
32*72 = 441
2^2 = 4
Exponents are used to replace repeated factors. Prime numbers won't use exponents because they don't have repeated factors. To express the prime factorization of a particular composite number using exponents, just count. 2 x 2 x 2 x 3 x 3 = 72 23 x 32 = 72
245 = 51 x 72
441 = 32 x 72
35 x 7 = 1701
