Question

The real roots of the equation $- p + q + r$ are.

• A. – 1, 4
• B. 1, 4
• C. – 4, 4
• D. None of these

Answer 1

Answer: (D)

None of these

Answer 2

$4^{x} - 3^{x\mspace{6mu} - \mspace{6mu}\frac{1}{2}} = 3^{x + \frac{1}{2}} - 2^{2x - 1}$ $\frac{4}{3}$

⇒ $\frac{3}{2}$, which is not possible. Hence, the given equation has no real root.
