Question

The integral I = ∫ 2 2 x + x d x = λ . 2 2 x + C (where, C is the constant of integration). Then the value of λ is equal to, 1 ln ⁡ 4, 1 ln ⁡ 2 2, 1 ln ⁡ 2, 1 ln ⁡ 4 2

Given, I = ∫ 2 2 x . 2 x d x Let, 2 2 x = t ⇒ 2 2 x . 2 x . ln ⁡ 2 2 d x = d t ⇒ 2 2 x . 2 x d x = d t ln ⁡ 2 2 Thus, I = ∫ d t ln ⁡ 2 2 = t ln ⁡ 2 2 + C = 2 2 x ln ⁡ 2 2 + C ∴ λ = 1 ln ⁡ 2 2 ⇒ λ = l ln ⁡ 2
