Question

Simplify each radical expression, if possible:

Answer 1

Answer:

C) cannot be simplified

Explanation

We want to simplify the radicals:

$\sqrt[3]{7} - \sqrt[4]{7}$

We can rewrite this as exponents:

${7}^{ \frac{1}{3} } - {7}^{ \frac{1}{4} }$

Since the base are the same but are subtracting, we do not have any rule of indices for subtracting unlike indices .

Therefore the expression cannot be simplified further.
