Question

x^1/4 = 5 x=?

Answer 1

1/4 (logx) = log 5
logx = (log5) / (1/4)
x= 625

Answer 2

thanx!

Answer 3

or just raise each side to the 4th power

Answer 4

I agree with mrjoselson: (x^1/4)^4 = 5^4 => x = 625

Answer 5

Yeah, typically you'd resort to logs when you have a variable in the exponent which isn't the case here. Not that you can't do it, but it seems more straight forward to just raise to the 4th

Answer 6

especially if the students haven't learned logs
