limits without lhopital - limxto0frac2frac1x+2frac1x3frac1x+3frac1x=?

fine the limits-without-lhopital rule



lim



My Try :




h= \frac{1}{x} :h\to - \infty



so :



\lim_{ h\to - \infty }\frac{2^{h}+2^{-h}}{3^{h}+3^{-h}}=?\\\lim_{ h\to - \infty}\frac{(2^{-h})2^{2h}+1}{(3^{-h})3^{2h}+1}=?\\\lim_{ h\to - \infty }\frac{(2^{-h})2^{2h}+1}{(3^{-h})3^{2h}+1}=?



now :?
