Answer 2

$\bf{\huge{\underline{Question}}}$

Simplify:

$( - 4 {x}^{2} {y}^{2}z) \times (3x {y}^{3} )$

$\bf{\huge{\underline{Answer}}}$

$( - 4 {x}^{2} {y}^{2}z) \times (3x {y}^{3}) \\ \implies - 4 \times 3 \times {x}^{2} \times x \times {y}^{2} \times {y}^{3} \times z \\ \implies - 12 \times {x}^{2 + 1} \times {y}^{2 + 3} \times z$

$\implies \rm{ \underline{ \boxed{\red{- 12 {x}^{3} {y}^{5} z}}}}$
