$( - 4 \sqrt{3) {}^2{} } - 4(3)(4)$
​

Answer 1

hope this is helpful.

Answer 2

$({3\sqrt{3}})^{2}-4(3)(4)$

AS you know

${\sqrt{x}}^{2}$=x

AS $\sqrt{x}$

IS only one And for square root it need a pair.
so when Multiply By same $\sqrt{x}$ number
It Become a pair and Become x

Just like in Above question

(-4√3)²-4(3)(4)
(-4²√3²)-12×4
(-4×-4×3)-48
(16×3)-48
48-48
=0

$\boxed{\textsf{Answer=0}}$
