The equation: T= 2* pi* sqrt(2/3L/9.8) Solve for L. Please show the solution step by step. The square root is giving me trouble in my solution. Thanks for your help.

If L is known:
1. Plugin the value of L.
2. Simplify the quantity under the radical.
3. Take the square root of the number
under the radical.
Example:
L = 19.6 m.
Solve for T.
T = 2pi*sqrt((2/3)*L/g)
T = 6.28*sqrt((2/3)*19.6/9.8) =
6.28*sqrt((2/3)*2) = 6.28*sqrt((4/3) =
6.28 * 1.1547 = 7.25 s.
