Find the unknown number in the equation 30,672 ÷ q = 852 explain how you found the unknown.

The value of q is 36.

Step-by-step explanation:

From the given equation,

            =  852

This also implies that,

            =

Cross multiply to have;

    q × 852 = 30672 ×1

     852q = 30672

Since the value of q is required, divide both sides by 852;

    q =

       = 36

Thus, the value of q is 36.

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)
