Respuesta es así:
2ˣ⁻¹ - 3√2ˣ⁻¹ + 2 = 0 x = 3 x = 1
______________________
Pasos
2ˣ⁻¹ - 3√2ˣ⁻¹ + 2 = 0
Vamos a reescribir la ecuación 2ˣ⁻¹ = u
u - 3√u + 2 = 0
Vamos a resolver u - 3√u + 2 = 0 u = 4 u = 1
u = 4 u = 1
Vamos a resolver
Siendo u = 2ˣ⁻¹ resolver la sgte para encontrar x
2ˣ⁻¹ = 4 x = 3
2ˣ⁻¹ = 4
Convertir 4 a base
4 = 2²
2ˣ⁻¹ = 2²
Resolver 2ˣ⁻¹ = 1 x = 1
Respuesta
x = 3 ; x = 1
