Brand A has a box of 36 spoons for $1.54. Brand B has a box of 48 spoons for $1.66. What’s the unit price for each brand?

brand a is $0.04 Brand b is $0.03

Step-by-step explanation:

cost of the box /number of spoons = unit price

Brand A=$0.04 Brand B=$0.03 per spoon

Step-by-step explanation:

Brand A: 1.54/36 =0.04 Divide the price by the number of spoons to get the price per spoon, or unit price

Brand B: 1.66/48 =0.03 Do the same thing for Brand B.

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)
