    Question no. 5 (iv) Dividing and multiplying by √7 + 2, we get
    1/(√7 - 2) = [1/(√7 - 2)] × (√7 + 2)/(√7 + 2)
    Using identity (a + b)(a - b) = (a² - b²)
    = (√7 + 2) / (√7)² - (2)²
    = (√7 + 2) / (7 - 4)
    = (√7 + 2) / 3

    Sir question no 3 ka ye answer nahi ho sakta hai?
    π=c/d
    When we major a line which scale get approximate value on the other hard decimal expansion of c/d is neither terminating or repeating
    Here, π is irrational
