Answer 2

for this case we must rewrite the following expression in algebraic form:

5 square root of x to the 7th power.

So, we have:

$5 \sqrt {x ^ 7} =$

We can rewrite:

$x ^ 7 = x ^ 6 * x$

By definition of properties of powers and roots we have:$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$5 \sqrt {x ^ 6 * x} =\\5x ^ 3 \sqrt {x}$

Answer:

$5x ^ 3 \sqrt {x}$
