Real world Radical Formula???

I have not been in math for a while and am a little lost. the problem is : C=4(23245)^-1/3 (13.50) I am not sure how to multiply 23245 by the negitive 1/3 exponent. This is the example from class: C = 4*d*-1/3*b *

C = 4(8500)-1/3(8.17)C = 4(.049)(8.17)

C = .196(8.17)

C = 1.60

Not sure how she got the .049. Please help.

how about graphing an exponential function ifexponent is a fraction F(x)=3 to (.5x)

How do you graph an exponential function if exponent is a fraction - problem is f(x)=3 to the .5x. So if x is 1, f(x) is square root of 3. If x is 2, f(x) is 3. If x is 3, f(x) is 3 times the square root of 3......but is there pointers to how to graph this?
