Question

(A) ધારો કે $l = \lim _{x \rightarrow 0} \frac{6^x-3^x-2^x+1}{x^2}$.અંશના અવયવો પાડતા:$6^x - 3^x - 2^x + 1 = 3^x(2^x - 1) - 1(2^x - 1) = (2^x - 1)(3^x

$(\log _e 2)(\log _e 3)$

Vedclass · Answer

(A) ધારો કે $l = \lim _{x ightarrow 0} \frac{6^x-3^x-2^x+1}{x^2}$.અંશના અવયવો પાડતા:$6^x - 3^x - 2^x + 1 = 3^x(2^x - 1) - 1(2^x - 1) = (2^x - 1)(3^x - 1)$.આ કિંમત લક્ષમાં મૂકતા:$l = \lim _{x ightarrow 0} \frac{(2^x - 1)(3^x - 1)}{x^2} = \lim _{x ightarrow 0} \left( \frac{2^x - 1}{x} ight) 	imes \left( \frac{3^x - 1}{x} ight)$.પ્રમાણિત લક્ષના સૂત્ર $\lim _{x ightarrow 0} \frac{a^x - 1}{x} = \log _e a$ નો ઉપયોગ કરતા:$l = (\log _e 2) 	imes (\log _e 3)$.

$\lim _{x \rightarrow 0} \frac{6^x-3^x-2^x+1}{x^2}$ ની કિંમત શોધો.
