Question

Which of the following is equivalent to the radical expression below?

Answer 1

For this case we must indicate an expression equivalent to:

$\sqrt {10x ^ 7}$

By definition of properties of powers and roots we have that:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

Then, we can rewrite the expression as:

$10 ^ {\frac {1} {2}} * x ^ {\frac {7} {2}}$
