MCQ
$\sqrt {\sqrt x + 1} $ નું વિકલન મેળવો.
- A${1 \over {\sqrt x (\sqrt x + 1)}}$
- B${1 \over {\sqrt x \sqrt {x + 1} }}$
- C${4 \over {\sqrt {x(\sqrt x + 1)} }}$
- ✓${1 \over {4\sqrt {x(\sqrt x + 1)} }}$
$\frac{{dy}}{{dx}} = \frac{1}{{2\sqrt {\sqrt x + 1} }}\frac{d}{{dx}}(\sqrt x + 1)$
$\frac{{dy}}{{dx}} = \frac{1}{{4\sqrt x .\sqrt {\sqrt x + 1} }} = \frac{1}{{4\sqrt {x(\sqrt x + 1)} }}$.
