Raj has a full deck of 52 cards. sydney chooses the queen of clubs and holds onto it. then yolanda chooses a card. what is the total number of possible outcomes for yolanda’s card?

51 cards.

Explanation:

Since, here initially total number of cards= 52

According to the question, Sydney chooses the queen of clubs and holds onto it.

That is, she chosen one card from 52 cards.

And, there is no replacement of this card, therefore remaining card = 51

Thus, If after that Yolanda chooses a card from these 51 cards then possible outcomes= 51.

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)
