Solution

The correct option is D $- 60 x^{2} y z^{2}$
We know that, $x \times x = x^{2}$ , $z \times z = z^{2}$ and
$5 \times (- 4) \times 3 = - 60$ .

$∴ 5 x \times (- 4 y z) \times 3 x z = - 60 x^{2} y z^{2}$

5 x \times (- 4 y z) \times 3 x z

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 $4 y z + 6 x z - 2 x y - 4 y + 5 x$ .
