- ✓$\log \left( {\frac{2}{3}} \right)$
- B$\frac{1}{2}\log \left( {\frac{3}{2}} \right)$
- C$\frac{1}{2}\log \left( {\frac{2}{3}} \right)$
- D$\log \,\left( {\frac{3}{2}} \right)$
Using $L-$ Hospital’s rule,
$y = \mathop {\lim }\limits_{x \to 0} \frac{{{4^x}\log 4 - {9^x}\log 9}}{{({4^x} + {9^x}) + x({4^x}\log 4 + {9^x}\log 9)}}$
==> $y = \frac{{\log 4 - \log 9}}{2}$
==> $y = \frac{{\log {{\left( {\frac{2}{3}} \right)}^2}}}{2} = \log \frac{2}{3}$.
