$$331,776$$
Step 1: Substitute $x=-3$, $y=4$ and $z=6$ $(2xy^{2}z)^{2}$ $(2*-3*4^{2}*6)^{2}$ Step 2: Remember the order of operations Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction So first, Since we do not have any parenthesis, we do exponents. So, $(2*-3*16*6)^{2}$ Step 3 Multiplication $(-576)^{2}$ Step 4 Finish the last exponent $331,776$
