Last year's student council officers sold 150 school logo bumper stickers. Bumper Sticker Sales Student Council Officer Number Sold President 14 Vice-President 15 Secretary 13 Treasurer 108 Based on the data above, which statement about the bumper sticker sales is misleading? A. The treasurer sold 72% of the bumper stickers last year. B. The average number of sales among the 4 students was 38 bumper stickers. C. The average number of sales is higher than the actual number of sales for 3 of the student council officers. D. The combined sales of the President and Vice-President make up close to 20% of the total bumper stickers sold.

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)

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
