I am confused on what they are asking

i think the answer is a....but im not completely sure
never mind I was write about A!
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)
√(5c) * √(15c^3) ?
then
= √(75c^4)
= √25 c^2 √3
= 5c^2 √3 , which would be C

I took the test and the test and answered A. I got it write. the problem is supposed to look like 3√5c*√15c^3
right not write XD I am terrible at english
ugh my english is terrible
It's a!
Yes, you are correct. The simplified form of 3√5c * √15c^3 is 15c^2 * √3, which is option A. Well done!
