1. The problem statement, all variables and given/known data
Ts=2π√4.5*10-2kg/2.0*103kg/s2

2. Relevant equations

3. The attempt at a solution
I just started Physics Yesterday and have no idea what to do.

That's not a problem statement.

I assume you are trying ro simplify the expression.
First, let's make the expression correct by using parentheses. I believe it should read Ts=2π√(4.5*10-2kg/(2.0*103kg/s2)).
Or more clearly, $2\pi\sqrt{\frac{4.5 *10^{-2}kg}{2 *10^3 kg s^{-2}}}$.
You can work with the numbers and the units separately. For the units it reduces to √(kg/(kg s-2)). Can you see how to simplify that?

@haruspex I am probably so late to this response that it might be a little silly to respond, but I feel as if I have to thank you because your answer, all those months ago, helped me realize what I was supposed to being doing. I honestly meant to respond soon after you posted but it somehow slipped my mind. Better late than never, right?
