Irrational Numbers a and b
Give an example of irrational numbers a and b such that the indicated expression is (a) rational and (b) irrational.
1. a + b
2. a•b
3. a/b
4. a - b
What exactly is this 4 part problem asking for?

Re: Irrational Numbers a and b
These are easier than you think. Make a rational answer
Eg root2/root2 is rational

Sounds good. Thanks again. I will return later with my work. Going to a job interview now.

I will a sample of each.
1. a + b
How about sqrt{2} + 3?
2. a•b
How about pi(9)?
3. a/b
How about e/5?
4. a - b
How about sqrt{5} - 1?
You say?

Re: Irrational Numbers a and b
Both a and b are supposed to be irrational.

You are right. Let me try again.
I will a sample of each.
1. a + b
How about sqrt{2} + sqrt{3}?
2. a•b
How about pi times e.
3. a/b
How about e/pi?
4. a - b
How about sqrt{5} - sqrt3}?
You say?

Re: Irrational Numbers a and b
Those will do for examples giving an irrational answer.
Now can do find examples where the answer is rational
Bob
Ps did I read in a post that I now cannot find that you have got a job. That's great!
