It is: 2*5*7 = 70 and no exponents are needed
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
It is 53 = 125
112 = 121
First you do the prime factorization without exponents. Then you use exponents to indicate repeated factors. For example, if a number has the prime factors 2 x 2 x 2 x 3 x 3 x 5, you write that as 23 x 32 x 5.
exponents can be found in math formulas and wen multiplying the same number. exponents can be found in math formulas and wen multiplying the same number.
