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?

Thanks for letting me know. It's nice to know I helped.
 
Stay gold, haruspex. Stay gold.
