what is the simplified form of 3 sqrt (5c) x sqrt (15c^3)
choices are
a. 15c^2 sqrt (3)
b.6c^2 sqrt (5)
c. 5c^2 sqrt(3)
d. 12c^4 sqrt(5)
please help i don't understand how to do the question
i would really appreciate it

3√(5c) (√(15c^3)
= 3√(75c^4)
= 3*√25*√3*c^2 , * implies multiplication
= 15√3 c^2 <==== better form than their choice a) 👍
