Answer:
1) = -6
2) = 12
Step-by-step explanation:
1) = (2a⁴b³)² (-3ab⁷)³
= 2a⁸b⁶(-3ab⁷)³
= 2a⁸b × -3a³b²¹
= -6a¹¹b²²
Coefficient is -6.
(4a²b³)²(3ab⁷)⁵²
= 4a⁴b⁶×3a⁵²b³⁶⁴
= 12a⁵⁶b³⁷⁰
Coefficient is 12.
Without complex calculation, we can find the coefficient by multiplying each coefficient of the product:
