Before answering the exact question you sent, you have to understand one simple principle: there are two forms of a variable with a fraction as an exponent, exponential form and radical form.
Example:
If the exponent is a fraction, the denominator of the fraction is the number on the outside of the radical sign.
So, for #23, you would change
to
. Then, because the a is the same after the 2 and the 3, you can add them up to get
.
For #24, you'd do almost the same thing (change the radical-b's to
and
. However, you can't add them up because the exponents are different (1/4 and 1/3), so you'd leave it as
