Answer:

D.
√(250)

Explanation:

First, use prime factorization of 250 to get
√(2*5^3)

Then apply the exponent rule,
a^(b+c) =a^(b)*a^(c)

=
√(2*5^2*5) }

Apply radical rule:
√(ab)= √(a) √(b), a\geq 0, b\geq 0

=
\sqrt{5^(2)} √(2*5)

Apply radical rule:
\sqrt{a^(2)} =a, a\geq 0

=5
√(2*5)

=5
√(10)
