The simplification of a³ - 1000b³ and 64a³ - 125b³ is (a - 10b) × (a² + 10ab + 100b²) and 4a - 5b) • (16a² + 20ab + 25b²) respectively.
<h3>
Simplification</h3>
Question 1: a³ - 1000b³
a³ - b³
= (a-b) × (a² +ab +b²)
- 1000 is the cube of 10
- a³ is the cube of a¹
- b³ is the cube of b¹
So,
(a - 10b) × (a² + 10ab + 100b²)
Question 2: 64a³ - 125b³
a³ - b³
= (a-b) × (a² +ab +b²)
- 64 is the cube of 4
- 125 is the cube of 5
- a³ is the cube of a¹
- b³ is the cube of b¹
So,
(4a - 5b) • (16a² + 20ab + 25b²)

Answer:
The final price of share is $84
Step-by-step explanation:
Initial price of share = $ 80
The price of share is dropped by 15% on Tuesday
Drop in share = 15 % of 80 = 0.15×80 = $12
Price of share after 15% drop in price = $80 -$12 = $ 68
Price of share increased by $7 on Wednesday
Price of share on Wednesday = $68 +$7 =$ 75
on Thursday the price of share was increased by 12%
So the price of share on Thursday = price of share + 12 % of price of share
= $75 +12 % of $ 75
= $75 +0.12 ×$ 75
= $ 75 +$9 = $ 84
The final price of share is $84
