60 seconds = 1 minute

60 minutes = 1 hour
5670 seconds =
hours

5670 seconds = 1.575 hours

Step-by-step explanation:

Given : 60 seconds = 1 minute

            60 minutes = 1 hour

To Find : 5670 seconds =  ? hours

Solution :

Since we are given that    

60 minutes = 1 hour

so,    (a)

and we are also given 60 seconds = 1 minute

So, using (a)

⇒

⇒

⇒

Thus , 5670 seconds = 1.575 hours

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)
