Question

$5x\times (-4yz)\times 3xz$ =.

• A. $-60x^{2}y{z}^2$
• B. $-60xyz$
• C. $-60x{y}^{2}z$

Answer 1

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

On multiplying $x$ with $x$, its power is raised to 2 i.e., $x\times x=x^2$
Similarly, on multiplying $z$ with $z$ its power is also raised to 2 .
i.e.,
$z\times z=z^2$
Now, as the main expression is primarily in multiplication, we multiply all the coefficients to get the final coefficient as $5\times (-4)\times 3=-60$

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