Some better less time consuming solns. Q19. 100²-99²+98²-97²+...+2²-1² = (100+99)1+(98+97)1+... So it is actually sum of first 100 natural numbers. Q27. x = 3 +2√2 = 2 + 2.√2.1+1 = (√2+1)² So, √x = √2 +1 and 1/√x = √2-1 So √x - 1/√x = √2 +1 -√2 + 1 = 2√2 Q40. x²-2xy =84 => x²-2xy+y²=84+y² => (x-y)²=84+y² => 84+y²=100 So, y²=16 And, y = 4
Thanx bdee bhaiii Is series ko continue rkhna bhaiii Mai bhai hmesha previous lgaya hu to kc lgte h kc nhii phir sochta hu ab kha se doubt clear kruu But ab ye video mil gyaa Thannx for this content

Q19. 100²-99²+98²-97²+...+2²-1²
= (100+99)1+(98+97)1+...
So it is actually sum of first 100 natural numbers.
Q27. x = 3 +2√2 = 2 + 2.√2.1+1 = (√2+1)²
So, √x = √2 +1
and 1/√x = √2-1
So √x - 1/√x = √2 +1 -√2 + 1 = 2√2
Q40. x²-2xy =84
=> x²-2xy+y²=84+y²
=> (x-y)²=84+y²
=> 84+y²=100
So, y²=16
And, y = 4
