Six times four less than three times x

18x - 24

Step-by-step explanation:

Three times x is 3x.

Four less than three times x is 3x - 4.

Six times four less than three times x is 6 * ( 3x - 4 ).

6 * ( 3x - 4 )

= 6 ( 3x ) + 6 ( - 4 )

= 18x - 24

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)
