Una persona viaja a la ciudad X a la ciudad Y de la siguiente manera: la mitad del recorrido lo realiza en tren, la tercera part
hodyreva [135]
Tenemos que

R------------ > recorrido total
x---------------- > viaje en tren--------------- > (1/2)*R 
y----------------- > viaje en bicicleta-------------(1/2)*(1/3)*R=(1/6)*R
z------------------- > viaje en automovil --------- > (1/2)*(2/3)*R=(2/6)*R=100 km
R=x+y+z
resolviendo nos queda que
(2/6)*R=100--------------- > R=100*6/2=300 km
viaje en tren----------- > (1/2)*R=300/2=150 km
viaje en bicicleta------- > (1/6)*R=300/6=50 km

E5 In (x + 1)<br> Simplify
pentagon [3]

Answer:

e^ (5 ln (x + 1))   = (x + 1)^5

Step-by-step explanation:

e5 In (x + 1)  or did you mean   e^ (5 ln (x + 1))

because then this would simplify a lot

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5)

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5) = (x + 1)^5

or did you mean  (e^5) ( ln (x + 1))  =  ln [(x+1)^(e^5)]

But I think you meant:

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5) = (x + 1)^5
