The area model below shows a way to solve 7,776 ÷ 24 using place value. The 3 partial quotients missing from the model represent hundreds, tens, and ones To find the quotient, the 3 partial quotients are added together. What is the quotient?

The answer is 324 all you have to do is just divide 7,776 by 24 then Breaking it into expanded form.

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

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)
