MCQ
If we multiply $5 x$ and $(-4 x y z),$ then we get:
- A$20 x^{2} y z$
- ✓$-20 x^{2} y z$
- C$x^{2} y z$
- D$-2 x y z$
✓
Answer
Correct option: B.
$-20 x^{2} y z$
b
$(5 x) \times(-4 x y z)$
$=5 \times x \times(-4) \times x \times y \times z$
$=-20 x^{1+1} y z$
$=-20 x^{2} y z$
$(5 x) \times(-4 x y z)$
$=5 \times x \times(-4) \times x \times y \times z$
$=-20 x^{1+1} y z$
$=-20 x^{2} y z$
