A IRRATIONAL CAN NOT BE WRITTEN AS A FRACTION
EXAMPLES:
PI
(SQUARE(2)
IF YOU CAN RAISE A NUMBER TO ANY OF THESE
YOU WOULD HAVE A IRRATIONAL EXPONENT

recall that, by definition, an exponent can be any number, real or complex, negative or positive, rational or , algebraic or transcendental.
is an example of an irrational exponent
or ....how to do this one?
we will do it by the exponent by exponents that are closer and closer to the irrational one
In example , you want the exponent to be equal to , so the first approximation to is .
or, go one step further with , so the second approximation to is which is approximately
or three significant figures,
, so you have to take a which is approximately Continuing this way, we get the sequence of approximations:
, , , , , , , ...
