Hi!

Next week I'm going to present the solution of a math problem to some foriegn visitors that are coming to our school. Thus, the presentation is going to be in English, and I'd be grateful for some help with terminolgy.

When you say f'(x), how do you pronounce it? Is it a short i or a long i?

When you want to say for instance a>x as a condition, do you use suppose or assume?

Do for a^n say a raised to the power of n, a raised to n or a to the power of n?

Thanks!
