Simplify. Multiply and remove all perfect squares from inside the square roots. Assume b is positive.

216*b^2

Step-by-step explanation:

first, remember that:

a*√b = √(a^2*b)

√a*√b = √(a*b)

Now, our expression is:

Where in the right I rewrite the expression so it is easier to work.

Now we can use the second property of the above ones, to have:

And we know that:

Then:

and 12*12 = 144, then:

false
