a. 51² - 50²
On comparing the given equation with ( a² - b² = { a + b }{ a - b} ) we get that a = 51 and b = 50
Therefore,
51² - 50²
→ ( 51 - 50 )( 51 + 50 )
→ ( 1 ) ( 101 )
→ 101
Answer : 101
b. 10² - 8²
On comparing comparing 10² - 8² with ( a² - b² = { a + b}{a - b } ) , we get that a = 10 and b = 8
Therefore
10² - 8²
→ ( 10 - 8 )( 10 + 8)
→ ( 2 ) ( 18 )
→ 36

51 square = 2601
50 square = 2500
2601 - 2500 = 101
10 square = 100
8 square = 64
100-64 = 36
50 square = 2500
2601 - 2500 = 101
10 square = 100
8 square = 64
100-64 = 36

it is so complicated method
why is it complicated
suppose some one ask 9975square-9876square then you will find the square
I don't think such questions will come
ok
if we do square formula then it would be so simpler than this
yes
