When you multiply a by a whole number, the denominator in the product is the same as the
of the fraction. The numerator in the product is the
of the whole number and the
of the fraction.
The words are fraction, product, whole number, denominator, numerator.

You multiply the numerator of the fraction by the whole number, then the denominator stays the same as the fraction. Then you divide the denominator into the numerator. How ever many times your denominator goes into your numerator then that’s your answer.

Step-by-step explanation:

the mean and mad

step-by-step explanation:

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)
