It takes 24 h to fill a large basin with two hoses, where the water

in one hose flows four times as

fast as the other hose. How long

will it take the slower hose to fill

the basin if the faster hose is not

functioning?

The answer is 72 hrs or 60 hrs

Step-by-step explanation:

Im not sure whether the answer is right. So you guys are gonna have to guess. :)

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
