If sam has 1 gallon of milk and he drinks 4 glass of 8 ounces how many dayswould he have drank the milk gone?

1 gallon = 4 quarts

1 quart = 32 ounces, 1 quart = 32 ounces*1 glass/8 ounces = 4 glasses

1 quart = 4 glasses

1 gallon = 4 quarts = 16 glasses

If Sam drinks 4 glasses per day. and he has 16 glasses, then 16/4 = 4 days

Answer is 4 days.

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:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
