How do you know how many points you have earned for the day?

u dont

Step-by-step explanation:

idk maybe u do but I'm pretty sure u dont

Should be in a little daily chart under 'your influence'.

Step-by-step explanation:

If not you could total up how many points the questions you answered today were altogether on a paper, they say the amount they are worth.

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)
