units/conversions/algebra help please

[math?]

hello, i am hoping to have someone confirm that my answer to these math questions are correct.

1. T=2pi[sqrt. of (540g(205cm)/9.81kg*m/s^2]

first i converted to similar units.

540g = .54kg

205cm = 2.05m

second - worked within sqrt.: [sqrt. of (.54kg(2.05m)/9.81kg*m/s^2] = [sqrt. of .113kg*m/s^2]

T = .336kg*m/s

thats my answer. i'm sorry if i am posting in the wrong category. i was sure exactly what level math this is. college tech math.

thanks in advance for your help.

How did kg and m get out of the Square Root alive? \(\displaystyle \frac{10\cdot kg}{1\cdot kg}\;=\;10\;\ne\;10\cdot kg\)

You may wish to make sure your parentheses match up before wondering if the arithmetic is correct.

You may wish to remember the definition of "T". Is it supposed be "seconds"?
