The 1. Order and Degree of the differential equation \(\sqrt{\frac{\mathrm{dy}}{\mathrm{d} x}}-4 \frac{\mathrm{dy}}{\mathrm{d} x}-7 x=0\) is respectively
- A 1,2
- B 2,1
- C 2,2
- D 3,1
Answer & Solution
Correct Answer
(A) 1,2
Step-by-step Solution
Detailed explanation
\(\sqrt{\frac{\mathrm{dy}}{\mathrm{d} x}} = 4 \frac{\mathrm{dy}}{\mathrm{d} x}+7 x\) \(\frac{\mathrm{dy}}{\mathrm{d} x} = \left(4 \frac{\mathrm{dy}}{\mathrm{d} x}+7 x\right)^2\)
