Step-by-step explanation:

Question :

How many numbers lie between squares of the number in each pair? 76 and 77

Solution :

To do this we have to find the squares if both the numbers and then subtract them.

➛ 76²

→ 76 X 76

→ (70 + 6) (70 + 6)

→ 70 X 70 + 70 X 6 + 6 X 70 + 6 X 6

→ 4900 + 420 + 420 + 36

→ 5776

➛ 77²

→ 77 X 77

→ (70 + 7) (70 + 7)

→ 70 X 70 + 70 X 7 + 7 X 70 + 7 X 7

→ 4900 + 490 + 490 + 49

→ 5929

↪ 77² - 76²

↪ 5929 - 5776

↪ 153

∴ 153 nos. lie between the squares of 76

and 77.
