Zach can mow 2 laws in one hour. How many lawns can he mow in 3 hours

well 2 x 3 is 6 so Zach can mow 6 lawns in 3 hours

Zach can mow 6 lawns in 3 hours.

Step-by-step explanation:

For each hour, he mows 2 lawns, so 3 hours times 2 lawns per hour equals 6 lawns mowed total.

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)
