JPancho 1) 2 Log x = 3 + Log (x/10) Aplicando propiedades de logarítmod 2 log x = 3 + log x - log 10 2 log x - log x = 3 - 1 log x = 2 x = 10^2 x = 100
2) 3 Logx - log 32 = log (x/2) 3 log x - log 2^5 = log x - log 2 3 log x - log x = - log 2 + 5 log 2 2 log x = 4log 2 log x = 2 log 2 x = 10^(2.log 2) x = 100^log2 log 2 = 0,3010 x = 100^(0,3010) x = 3,999
1)
2) 3log x - log 32 = log x -log 2
3logx -logx = log32 -log2
2logx = log 30
Saludos!!!
1) 2 Log x = 3 + Log (x/10)
Aplicando propiedades de logarítmod
2 log x = 3 + log x - log 10
2 log x - log x = 3 - 1
log x = 2
x = 10^2
x = 100
2) 3 Logx - log 32 = log (x/2)
3 log x - log 2^5 = log x - log 2
3 log x - log x = - log 2 + 5 log 2
2 log x = 4log 2
log x = 2 log 2
x = 10^(2.log 2)
x = 100^log2
log 2 = 0,3010
x = 100^(0,3010)
x = 3,999
