Question

FIND THE PRIME FACTORIZATION OF 245 USING EXPONENTS WHEN REPEATED FACTORS APPEAR

Answer 1

5*7*7?

Answer 2

One approach is to start dividing by primes: 2,3,5,7,11,13,...
Should not need to continue testing anything bigger than sqrt(245) = 15.6

Answer 3

Yes your factorization looks correct Ruby.
Each prime factor should only appear once though.

What's another way we could write 7*7 ?

Answer 4

Well done. They ask for exponents when repeated factors occur, so 7*7= ?.

Answer 5

7^2
