Answer:
The correct answer is D. 6r √qr
Step-by-step explanation:
Let's find out the equivalent to √12qr² * √3r
Let's recall that one of the properties of the roots is:
√a * √b = √a * b, for all positive real numbers a and b.
Therefore,
√12qr² * √3r = √(12qr² * 3r)
√(12qr² * 3r) = √36qr³
√36qr³ = 6r √qr
The correct answer is D. 6r √qr
