Question

Simplify (4x5y³)(-3x³y²).
O-12x85
Ox³y5
O-12x³y6
O-12x¹5,6

Answer 1

-12x⁸y⁵

Explanation:

Exponent law:

xᵃ * xᵇ = xᵃ ⁺ ᵇ

In exponent multiplication, if bases are same, add the exponents.

• Multiply the co-efficient.
• Multiply the variable using the exponent law.

(4x⁵y³) (-3x³y²) = 4*(-3) * x⁵⁺³ * y³⁺²

= -12x⁸y⁵
