Which expression shows the result of applying the distributive property to –2x(7 + 12)?
A. -14x – 24x
B. -14x + 24
C. -2x - 24x
D. -14x + 12

The closest answer is ;

A. -14x - 24x

which also equals to -38x

Step-by-step explanation:

Distributive property states ; a ( b + c ) = a b + a c

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)
