What is the simplified form of 3 Start Root 5 c End Root times Start Root 15 c cubed End root?

A. 15 c squared Start Root 3 End Root
B. 6 c squared Start Root 5 End Root
C. 5 c squared Start Root 3 End Root
D. 12 c superscript 4 baseline Start Root 5 End Root

I am confused on what they are asking

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)

right not write XD I am terrible at english

i think the answer is a....but im not completely sure

never mind I was write about A!

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

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!

The question is asking for the simplified form of the expression: 3√5c √(15c^3). To simplify this expression, we need to apply the rules of exponents and simplify the radicals.

First, let's simplify the radical √(15c^3):

Split the factors inside the radical:
√(15) √(c^3)

Evaluate the perfect square:
√(15) c √(c^2)

Simplify the radical:
c√(15c^2)

Now, substitute this simplified radical into the original expression:

3√5c √(15c^3) becomes:
3√5c (c√(15c^2))

Multiply the coefficients:
3 * c = 3c

Multiply the radicals:
√5 √(15c^2) = √(5 * 15c^2)

Combine the like terms inside the radical:
√(75c^2)

Simplify the radical:
√(25 * 3c^2)

Take out the perfect square from the radical:
√25 * √(3c^2)

Evaluate the perfect square:
5 * c

Combine the simplified radical with the coefficient:
3c * 5c = 15c^2

So, the simplified form of the expression is 15c^2. Therefore, the correct answer is A. 15c squared Start Root 3 End Root.
