  1. Question 1

    Q1. Find the derivative of (2x + 1)^(1/2)

    • A) 1 / √(2x + 1)
    • B) 1 / (2x + 1)
    • C) 1 / (2√(2x + 1))
    • D) 1 / (2x + 1)²

    Answer: 1 / (2√(2x + 1))

    Explanation: Using chain rule, d((2x + 1)^(1/2))/dx = (1/2)(2x + 1)^(-1/2) * d(2x + 1)/dx = 1 / (2√(2x + 1))
