MCQ
$27^{cos2x}81^{sin2x }$ ની ન્યૂનતમ કિંમત....... છે.
- ✓$1/243$
- B$1/27$
- C$-5$
- D$1/5$
હવે ${\rm{3 cos 2x + 4 sin 2x }}$ ની ન્યુનતમ કિમંત $ = \,\, - \,\sqrt {{3^2}\, + \,{4^2}} \,\, = \,\, - 5$
$\therefore {\rm{ 2}}{{\rm{7}}^{{\rm{cos2x}}}}{\rm{8}}{{\rm{1}}^{{\rm{sin2x}}}}\,$ ની ન્યુનતમ કિમંત $ = \,\,{3^{ - 5}}\,\, = \,\,\frac{1}{{243}}$
