Which choice is the solution to the inequality below? 2x < 30
A. x > 30
B. x < 30
C. X> 15
O D. x< 15
SUE

D

Step-by-step explanation:

Dividing the inequality by 2 to get rid of the coefficient of x we get x < 15.

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)
