Answer:

24

Step-by-step explanation:

This is just a radical.

[tex]3\sqrt{64}[/tex].

Radicals are formed by dividing a number into a perfect square, then taking the square root of it and putting it outside the sign.

This means that the value for this will be [tex]\sqrt{3^2 \cdot 64}[/tex]

[tex]3^2 = 9\\\\64\cdot 9 = 576[/tex]

And the square root of 576 is 24 (as [tex]24\cdot 24 = 576[/tex]).

Hope this helped!
