heres the equation

anonymous · Answer

First you have to simplify sqrt(45) and sqrt(28)
Are you able to give me the first steps in doing that?

anonymous · Answer

We can start by finding the prime factors of 45

3x3x5

And the prime factors of 28

7x2x2

Because there are 2 "3s," we can take one out

3sqrt(5)

Because there are 2 "2s," we can take one out

2sqrt(7)

Are you with me so far?
