Question

Does anyone know how to do this?

Answer 1

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
