Here are the solutions for parts (ক) and (খ). a) Step 1: Rearrange the given equation to find x + (1)/(x). Given the equation: x^2 - sqrt(3)x + 1 = 0 Since x=0 would lead to 1=0, which is false, we know x ≠ 0. We can divide the entire equation by x: (x^2)/(x) - sqrt(3)xx + (1)/(x) = (0)/(x) x - sqrt(3) + (1)/(x) = 0 Add sqrt(3) to both sides: x + (1)/(x) = sqrt(3) The value of x + (1)/(x) is sqrt(3). b) Step 1: Use the result from part (a) to find x^2 + (1)/(x^2). From part (a), we have x + (1)/(x) = sqrt(3). Square both sides of this equation: (x + (1)/(x))^2 = (sqrt(3))^2 Expand the left side using the formula (a+b)^2 = a^2 + 2ab + b^2: x^2 + 2 · x · (1)/(x) + ((1)/(x))^2 = 3 x^2 + 2 + (1)/(x^2) = 3 Subtract 2 from both sides: x^2 + (1)/(x^2) = 3 - 2 x^2 + (1)/(x^2) = 1 The value of x^2 + (1)/(x^2) is 1.
