1 Write each expression simplify when possible. 23. 24.
Oduvanchick [21]
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:
exponential\ form = x^{1/3}\\radical form =  \sqrt[3]{x}

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 \sqrt[3]{a} to a^{1/3}. Then, because the a is the same after the 2 and the 3, you can add them up to get 5 a^{1/3}.

For #24, you'd do almost the same thing (change the radical-b's to b^{1/4} and b^{1/3}. However, you can't add them up because the exponents are different (1/4 and 1/3), so you'd leave it as 3b^{1/4} - b^{1/3}
