Sasha works as a babysitter. She charges $20 for the job plus an additional $5 per hour. Sasha and her family will soon be leaving for vacation, and Sasha would like to have at least $70 for spending money. How many hours does Sasha need to work to earn her goal?

She would have to work 10 hours.

Step-by-step explanation:

She charges 20 to do the job but 5 for every hour well she already has 20 cause thats what she charges to do the job and sine 5x10=50

50+20=$70 so she will need to work 10 hours to be able to spend $70 on trip

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)
