Download Solution PDFसंकल्पना:
श्रृंखला नियम:
\(\rm \frac{d}{dx}[f(g(x))]= f'(g(x)) g'(x)\)
गणना:
यहाँ, -log (log x), x > 1
माना कि, log x = y है।
x के संबंध में अवकलन करने पर, हमें निम्न प्राप्त होता है
⇒ dy/dx = 1/x ....(1)
अब, -log (log x) = -log y
\(\rm \frac{d}{dx}(-\log y)=-\frac{1}{y}\frac{dy}{dx}\\ \)
= -1 / (x log x) ....((1) से)
अतः विकल्प (1) सही है।
