Question

Log5 ( 2x + 3) = log5 (11) + log 5 (3)​

Answer 1

Respuesta:

x = 4

Explicación paso a paso:

Log (2x +3) = log 14

2x + 3 = 14

2x = 17

x = 17/2

Answer 2

Respuesta:

$x=\frac{11}{2}$

Explicación paso a paso:

$\log _{10}\left(5\right)\left(2x+3\right)=\log _{10}\left(5\right)\left(11\right)+\log _{10}\left(5\right)\left(3\right)\\\\\log _{10}\left(5\right)\left(2x+3\right)=14\log _{10}\left(5\right)\\\\\frac{\log _{10}\left(5\right)\left(2x+3\right)}{\log _{10}\left(5\right)}=\frac{14\log _{10}\left(5\right)}{\log _{10}\left(5\right)}\\\\2x+3=14\\\\2x=11\\\\x=\frac{11}{2}$

Espero que te sirva! ❤
