Aroofer calculates his bid price using the formula p = 1.85s + 4.2f, where s is the area of the roof in square feet and f is the length of the fascia in feet. find the area of the roof with 190 feet of fascia and a price of $4,148. round to the nearest square foot. a. 1,811 ft2 b. 904 ft2 c. 2,674 ft2 d. 1,071 ft

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

60/10=x=6

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)
