1/4*8/9 please help Ill give points​

1/4 x 8/9 = 2/9

Step-by-step explanation:

1/4 x 8/9 = 8/36 = 2/9

2/9

Step-by-step explanation:

1/4 * 8/9

1 * 8 = 8

4 * 9 = 36

8/36 = 4/18 = 2/9

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)
