There is a mistake in step #1 of the solving process below. {x^2} - 4x = 171\\{x^2} - 4x + 4 = 172\\{\left( {x - 2} \right)^2} = 173\\x - 2 = \pm \sqrt {17} 4\\x = 2 \pm \sqrt {17} x 2 −4x=171 x 2 −4x+4=172 (x−2) 2 =173 x−2= ± 17 4 x=2± 17 true or false

step-by-step explanation:

if x = 2 you have to find x to finish the problem

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)

answer: get a conversion sheet out i dont know the exact measurments

step-by-step explanation: divide the number of feet with the nu,ber of milrs and there your answer

b. f(x) = –√x + 3this is the correct answer
