find the prime factorization of 45?

first split 45 into a pproduct of 2 no.s here 9 n 5
i.e., 45=9x5
now split one of the no.s here its 9
i.e., 45=(3x3)x5
therefore ur ans is 3x3x5 or 3^2x5...best of luck!

45 = 3 x 3 x 5

3 x 3 x 5

3 and 5 are the primes in 45

45=3*3*5
45 =3^2*5
that was easy

45 = 3² * 5

9 x 5
Factor out 9 which is 3 x 3
Prime factor is: 3 x 3 x 5 or 3^2 x 5

Hope that helps!
