Answer:
D.
Step-by-step explanation:
First, use prime factorization of 250 to get
Then apply the exponent rule,
=
Apply radical rule:
=
Apply radical rule:
=5
=5
So first factor it
1008=2*2*2*2*3*3*7
group them in similar pairs
1008=(2*2)(2*2)(3*3)*7
now remember we can do
so
=
2*2*3*
=
12√7
the answer is B
1008=2*2*2*2*3*3*7
group them in similar pairs
1008=(2*2)(2*2)(3*3)*7
now remember we can do
2*2*3*
12√7
the answer is B
