    This is how I pronounce them...

    \mathbb{R}^2 : "R" two
    \mathbb{R}^3 : "R" three
    \mathbb{R}^n : "R" "n"

    I called it as:

    \mathbb{R}^1 = " \mathbb{R}to the power of one"
    \mathbb{R}^2 = " \mathbb{R}to the power of two"
    \mathbb{R}^3 = " \mathbb{R}to the power of three"
    \mathbb{R}^n = " \mathbb{R}to the power of n"

    And so on.

    There are a few "special" ones in English.

    R^2 = "R squared" or "R to the second"
    R^3 = "R cubed" or "R to the third"

    Two and three are the only ones that I know of that have a "special" word like squared and cubed. Anything else is like this:

    R^4 = "R to the fourth"
    R^5 = "R to the fifth"

    I speak U.S. English, for whatever that's worth. The Brits and Aussies and all of those guys probably use something different :-D
