I got this question for homework and can't solve it please help
Find the size of the following sets
1.{x|x∈Z and x^2=8}.
2.P(A), where A=P({1,2}).
3.{1,10,100,1000,…}.
4.S×T, where S={a,b,c} and T={1,2,3,4,5}.
5.{x|x∈Z and x^2<8}.

Welcome to MSE. It will be more likely that you will get an answer if you show us that you made an effort. This should be added to the question rather than in the comments.

- Solve the equation for x.
- Calculate P(A) and count the sets.
- That set = { 10$^n$ : n nonnegative integer }.
- Prove |A×B| = |A|×|B|.
- One by one find the integers with square < 2.
How far will you have to look?
