Bottom 2? ? double points in for tomorrow, awarding brainiest

A)
a³ * a⁵ = a⁵⁺³
= a⁸

b)
b⁶ / b³ = b⁶⁻³
= b³

c)
4c⁷ * 3c⁵ = (4 * 3)c⁷⁺⁵
= 12c¹²

d)
12p⁶ / 4p² = (12 / 4)p⁶⁻²
= 3p⁴

e)
(3p²q³)³ = (3)³(p²)³(q³)³
= 27p²⁽³⁾q³⁽³⁾
= 27p⁶q⁹

f)
Shaded area = Area of large rectangle - Area of smaller rectangle
Area of large rectangle = 5(4x - 2)
= 20x - 10
Area of smaller rectangle = 3(2x - 3)
= 6x - 9
Shaded area = (20x - 10) - (6x - 9)
= 20x - 6x - 10 + 9
= 14x - 1
