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.

Step-by-step explanation:

Without complex calculation, we can find the coefficient by multiplying each coefficient of the product:

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
