Factor completely 45w^2?

Question

I realy do not understand. Does it mean like breaking it down like 5*3*3*w*w

Is this right, Please help me

Answer 1

I don't see anything else you can do, if 45w^2 is the whole of the expression to be factorised. That is certainly right, but even when giving prime factors, you don't normally remove the powers, and so I would guess the normal way of writing the answer was:

5 * 3^2 * w^2.
