Oblicz ( Nie same odpowiedzi :-) )[latex] a) frac{log_{6}4+2log_{6}3 }{log12-log frac{6}{5} } b) 9 ^{1-log_{3}5 } [/latex]

a) [latex] frac{log x_{6}(4*3*2) }{log10} = frac{2}{1} =2 [/latex] b[latex](3^{2} )^{1-log_{3}5} = 3^{2-2log_{3}5 }=9* frac{1}{3^{2log x_{3} 5} } =9* frac{1}{25}= frac{9}{25} [/latex]
