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.
32*72 = 441
22*72 = 196
2^2 = 4
75 = 3 x 52
22 x 32 = 36
2 x 72 = 98
35 x 7 = 1701
