Réponse : Bonsoir,

[tex]\displaystyle e^{5+(3-\ln 4) \times \ln 3}=e^{5+3\ln 3-\ln 4 \times \ln 3}=e^{5}e^{3 \ln 3}(e^{\ln 3})^{- \ln 4}=e^{5}3^{3}\frac{1}{(e^{\ln 3})^{\ln 4}}\\=\frac{27 e^{5}}{3^{\ln 4}}=\frac{27e^{5}}{3^{2 \ln 2}}=\frac{3^{3}e^{5}}{3^{2 \ln 2}}=3^{3-2 \ln 2}e^{5} \approx 873,8[/tex]
