Download Solution PDFजर फल \(f(x) =\frac{m}{x} +2nx + 1\) चा विकलज x = 2 वर शून्य होत असेल, तर m + 8n चे मूल्य काय आहे?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFगणना:
⇒ \(\displaystyle f(x) =\frac{m}{x} +2nx + 1\)
⇒ \(\displaystyle f'(x) =\frac{-m}{x^2} +2n\)
x = 2 वर विकलज शून्य होतो, म्हणून, f'(2) = 0
⇒ \(\displaystyle f'(2) =\frac{-m}{2^2} +2n=0\)
⇒ \(\displaystyle f'(2) =\frac{{-m} +8n}{4}=0\)
⇒ m = 8n
∴ अपर्याप्त माहितीमुळे m + 8n चे मूल्य ठरवता येत नाही.
