homework help

the resonant frequency of a circuit may be found by the formula f=1/ (2pie times the square root of LC) find the resonant frequency, to the nearest thousand of a circuit if L=7.062 x10^-5 C= 4.6 x10^-10.
so the set up is 1/ (2pie the square root of (7.062 x10^-5)(4.6 x10^-10)) i cant figure out for the life of me what i am doing wrong when multiplying. please help, thank you

How do you know you're doing anything wrong? If you meant the square root to be applied to LC (whereas you applied it to just L in your expression), Google calculator gives 1/(2pi*sqrt((7.062*10^-5)(4.6*10^-10))) = 883033.865.
