Game. Tina also worked out the total number of points scored by the 16 students in the
Here is her working.
(0 x 1) + (1 x 3) + (2 X 5) + (3 x 4) +(4 x 3) = 1 + 3 + 10 + 12 + 12 = 38
Tina made a mistake in her working to find the total number of points scored.
(b) Describe the mistake that Tina made.

Step-by-step explanation:

im lokking for a gf , i am 16

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)
