Pembahasan :
(-5x²)(-6xy)
= (-5)(-6) x³y
= 30x³y

————————————————
M² . M³ . M⁴
= m^(2 + 3 + 4)
= M⁹

————————————————
(-2X²Y²).(-2X²Y²)
= (-2x²y²)²
= (-2)² (x²)² (y²)²
= 4x⁴y⁴

————————————————
(2b/3a²).(2b/3a²).(2b/3a²)
= (2b/3a²)³
= (2³b³/3³a⁶)
= (8b³/27a⁶)

————————————————
(6xy).(-2xy).(4y²)
= (6)(-2)(4)x²y⁴
= -48x²y⁴

————————————————
(-3x²).(-xy²)³
= (-3)(-1)x^(2 + 3)y⁶
= 3x⁵y⁶
