How can I Find the size of each of the following sets [closed]
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}.

- 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?
Thank you very much this help me a lot note its <8 not <2
