\[\log{\frac{75}{16}}-2\log{\frac{5}{9}}+\log{\frac{32}{243}}=\log{2}\]
1
Usa Regla del Exponente: log⁡bxc=clog⁡bx\log_{b}{{x}^{c}}=c\log_{b}{x}.
log⁡7516−log⁡(59)2+log⁡32243=log⁡2\log{\frac{75}{16}}-\log{{(\frac{5}{9})}^{2}}+\log{\frac{32}{243}}=\log{2}

2
Usa Propiedad de la División Distributiva: (xy)a=xaya{(\frac{x}{y})}^{a}=\frac{{x}^{a}}{{y}^{a}}.
log⁡7516−log⁡5292+log⁡32243=log⁡2\log{\frac{75}{16}}-\log{\frac{{5}^{2}}{{9}^{2}}}+\log{\frac{32}{243}}=\log{2}

3
Simplifica  52{5}^{2}  a  2525.
log⁡7516−log⁡2592+log⁡32243=log⁡2\log{\frac{75}{16}}-\log{\frac{25}{{9}^{2}}}+\log{\frac{32}{243}}=\log{2}

4
Simplifica  92{9}^{2}  a  8181.
log⁡7516−log⁡2581+log⁡32243=log⁡2\log{\frac{75}{16}}-\log{\frac{25}{81}}+\log{\frac{32}{243}}=\log{2}

5
Usa Regla del Producto: log⁡b(xy)=log⁡bx+log⁡by\log_{b}{(xy)}=\log_{b}{x}+\log_{b}{y}.
log⁡(75162581×32243)=log⁡2\log{(\frac{\frac{\frac{75}{16}}{25}}{81}\times \frac{32}{243})}=\log{2}

6
Simplifica  75162581\frac{\frac{\frac{75}{16}}{25}}{81}  a  7516×25×81\frac{75}{16\times 25\times 81}.
log⁡(7516×25×81×32243)=log⁡2\log{(\frac{75}{16\times 25\times 81}\times \frac{32}{243})}=\log{2}

7
Simplifica  16×2516\times 25  a  400400.
log⁡(75400×81×32243)=log⁡2\log{(\frac{75}{400\times 81}\times \frac{32}{243})}=\log{2}

8
Simplifica  400×81400\times 81  a  3240032400.
log⁡(7532400×32243)=log⁡2\log{(\frac{75}{32400}\times \frac{32}{243})}=\log{2}

9
Simplifica  7532400\frac{75}{32400}  a  1432\frac{1}{432}.
log⁡(1432×32243)=log⁡2\log{(\frac{1}{432}\times \frac{32}{243})}=\log{2}

10
Usa esta regla: ab×cd=acbd\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}.
log⁡(1×32432×243)=log⁡2\log{(\frac{1\times 32}{432\times 243})}=\log{2}

11
Simplifica  1×321\times 32  a  3232.
log⁡(32432×243)=log⁡2\log{(\frac{32}{432\times 243})}=\log{2}

12
Simplifica  432×243432\times 243  a  104976104976.
log⁡32104976=log⁡2\log{\frac{32}{104976}}=\log{2}

13
Simplifica  32104976\frac{32}{104976}  a  26561\frac{2}{6561}.
log⁡26561=log⁡2\log{\frac{2}{6561}}=\log{2}

14
Ya que log⁡26561=log⁡2\log{\frac{2}{6561}}=\log{2} es falso, no hay ninguna solución.
