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}}`

Answer:
