never mind I was write about A!
Answered by Reiny
did you mean:
√(5c) * √(15c^3) ?
then
= √(75c^4)
= √25 c^2 √3
= 5c^2 √3 , which would be C

I am on a Mac and I can create √ with "Option v"
on a PC there are similar ways, google it
you could also do something like sqrt(5c) * sqrt(15c^2)

Yes, you are correct. The simplified form of 3√5c * √15c^3 is 15c^2 * √3, which is option A. Well done!
