Question

Find the product: $(-3axy)\times (-15a^2{xy}^{2}z)$

• A. $-45a^3{x}^2{y}^{3}z$
• B. $-45a^2{x}^2{y}^2$
• C. $45a^3{x}^2{y}^{3}z$
• D. $-45a{x}^2{y}^{2}z$

Answer 1

The correct option is C $45a^3{x}^2{y}^{3}z$

Required product $=(-3axy)\times (-15a^2{xy}^{2}z)$
=$(-3\times -15)\times (a\times a^2)\times (x\times x)\times (y\times y^2)\times z$
$=45a^3{x}^2{y}^{3}z$.
