The age of Noelle’s dad is six less than three times Noelle’s age. The sum of their ages is sixty-two. Find their ages.

Noelle is 17 years old and Noelle's dad is 45 years old.

Step-by-step explanation:

Noelle +    Dad    = 62

N      +    D      = 62

              ||

N      +  (3N-6)   = 62  

N + 3N - 6 = 62

4N = 62 + 6 = 68    >  N = 68%2F4 = 17.

 Noelle's dad;  3*17-6 = 45 years.

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)

the answer is 62.8 cubic units
