logx(1/27) = - 2 হলে x/3 = কত?
Solution
Correct Answer: Option B
logx(1/27) = - 2
বা, x - 2 = 1/27
বা, 1/x2 = 1/27
বা, x2 = 27
বা, x = √27
বা, x = √(9 × 3)
বা, x = 3√3
বা, x/3 = 3√3/3
∴ x/3 = √3
বা, x - 2 = 1/27
বা, 1/x2 = 1/27
বা, x2 = 27
বা, x = √27
বা, x = √(9 × 3)
বা, x = 3√3
বা, x/3 = 3√3/3
∴ x/3 = √3
