B12 apply real number exponents in expressions and equations
Originator: Ashlie M.
Explanition: A real number can be in the form of decimals, rational(like 42, or -26/27) and irrational numbers(like square roots or 
). Basically, any form other than unreal, or imaginary numbers.
ex.
the square root of 4 is 2 to the second power
then you can set the exponents equal to each other now that their bases are the same and solve for x

Ashlie, this is a good start. Just need to finish off you sample question. You may want to add a bit more to your explaination. Something like, "the exponent in an expression or an equation can be any real number... for example 3^(1/2), 3^(1.5), 3^(sqrt(2)), etc."
