Which equation represents this problem?

during a basketball game, rea scores two less than five times the number of goals that ben scores. rea scores 18 goals. how many goals does ben score?

let b = the number of goals ben scores.

b–2=18b–2=18

b–5=18b–5=18

2b–5=182b–5=18

5b–2=18

The expressions B-.18B and .82B each could represent how much Bo pays for the game.

Step-by-step explanation:

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)
