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 = 4-1/3db

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.
