I am giving the answer of the first one bcz points are not enough...

Answer 2

Answer:

Hey mate! Here's your answer:

Step-by-step explanation:

1) (3x - 4y)³

By using (a - b)³ = a³ - b³ - 3ab(a - b), where a = 3x and b = 4y,

(3x)³ - (4y)³ - 3(3x)(4y)(3x - 4y)

27x³ - 64y³ - 36xy(3x - 4y)

27x³ - 64y³ - 108x²y + 144xy².

2) (9x - 8y)³

Again, by (a - b)³ = a³ - b³ - 3ab(a - b), where a = 9x and b = 8y,

(9x)³ - (8y)³ - 3(9x)(8y)(9x - 8y)

729x³ - 512y³ - 216xy(9x - 8y)

729x³ - 512y³ - 1944x²y + 1728xy².
