If you mean 7^2 then 2 is the exponent and it means 7*7 = 49
Exponents count the number of repeated factors. 2 x 2 x 2 x 3 x 3 = 72 2^3 x 3^2 = 72
23*32 = 72
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
23 x 32 = 72
23 x 32 = 72
As a product of its prime factors in exponents: 23*32 = 72
49 = 72
72 = 49
33 x 72 = 1323
49 = 72
72 * 112
23 x 32
