Question

Simplify the problem sqrt 245c^5

Answer 1

Answer: the answer above is pretty much right, the answe is B

Answer 2

we have that
√[245c^5]-------> √245*√c^5

we know that
245-----> 5*7²
c^5---- c²*c²*c
so
√245-----> √[5*7²]----> 7√5
√c^5----> √[c²*c²*c]---> c²√c

√245*√c^5-----> [7√5]*[c²√c]----> 7c²√(5c)

the answer is
7c²√(5c)
