Solution

The correct option is D
$- 60 x^{2} y z^{2}$

On multiplying $x$ with $x$ , its power is raised to 2 i.e., $x \times x = x^{2}$
On multiplying $z$ with $z$ its power is also raised to 2 .
i.e.,
$z \times z = z^{2}$
Multiply all the coefficients to get $5 \times (- 4) \times 3 = - 60$

Therefore, the answer is $- 60 x^{2} y z^{2}$ .

$5 x \times (- 4 y z) \times 3 x z$ = ___ $x^{2} y z^{2}$

Solve the following:
Add $7 x y + 5 y z - 3 z x, 4 y z + 9 z x - 4 y, - 3 x z + 5 x - 2 y$

When $4 y z + 9 z x - 4 y$ and $- 3 x z + 5 x - 2 x y$ are added, we get $4 y z + 6 x z - 2 x y - 4 y + 5 x$ .
