Crop yield is the ratio of the number of bushels harvested to the number of acres used for the harvest. This year, the harvest at a farm was 94,010 bushels of grain, resulting in a crop yield of 170 bushels per acre. To the nearest whole acre, how many acres were harvested? 453 acres 489 acres 509 acres 553 acres

A total of 553 acres were harvested.

Step-by-step explanation:

Since the farm harvested a total of brushels of grain and the crop yield was brushels per acre, that means that the number of acre harvested is the division of the total number of brushels by the crop yield. This is done below:

A total of 553 acres were harvested.

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:

just sum

10 + 10 = 20
