Ejercicio 3;
Log(8) (x³y⁴)/z⁵
Log(8) x³y⁴ - log(8) z⁵
Respuesta → Log(8) x³y⁴ - log(8) z⁵
Ejercicio 4;
Log(25) x = 1/2
25¹/² = x
5 = x
Ejercicio b ;
Log(2) (5x-3) = 5
2⁵ = 5x-3
35= 5x
x = 7
Ejercicio 5;
6^x = 7776
Ln6^x = Ln7776
xln6 = ln7776
x = ln7776/ln6
x = 5
Ejercicio b;
80(5.4)^y = 7800
Ln80(5.4)^y = ln7800
yln80(5.4)= ln7800
y = (ln7800)/(ln80(5.4))
y = 1.4768
y ≈ 1.4
