Question

help! Find A and B if A = φ and B = φ2.
ty eddy need to see solution.

Answer 1

@Eddy: What is φ ? Is is somehow related to Euler's φ function?

Answer 2

I think it is 0
because \[\phi = 0\] in the set theory but I maybe mistaken ofc..

Answer 3

The Euler's phi function (that I remember) of a positive integer x has to do with the number of positive integers not greater than x and relatively prime to x.

Answer 4

So what should be the answer according?

Answer 5

I don't know that the phi function has anything to do with Eddy's problem. I saw the φ2 and thought about Euler's Phi function.Eddy needs to tell us what φ2 means in the context of his question.

Answer 6

Hmm true, it is applicable both ways, might even be something related to physics lol.
