Question

I need help on number 12

Answer 1

That picture is a little confusing, if you were trying to solve:

(c^2)^(1/2)=4608^(1/2)  (basically it look as if you were trying to simplify the right side...

find the prime factorization of 4608 and see how many perfect squares there are...

4608=2*2*2*2*2*2*2*2*2*3*3=256*9*2 so

c=(16^2*3^2*2)^(1/2)

c=4(3)(2^(1/2))

c=12(2^(1/2))
