3 x 7 = 21
(98) = 2 * (49) = 7 * 7 ( both primes, end sequence) so > prime factors are : 21 * 72
Oh, dude, prime factorization, really? Alright, so 22 can be broken down into 2 x 11. To write it with exponents, you'd have 2^1 x 11^1. So, there you go, prime factorization of 22 with a sprinkle of exponents.
The prime factorization for 21 is: 3x73 x 7 = 21
The prime factors of 90 in exponential form are 21 x 32 x 51.
The prime factorization of 50 using exponents is 21 x 52
3 x 7 = 21 No exponents necessary.
3 x 7 = 21
21 x 33
10 = 21*51
250 = 21 x 53
21 x 831 = 166
It is: 21*71*111 = 154
1250 = 21 x 54
54 = 21 x 33
18 = 21 x 32
14 = 21 x 71
