lim_(x rarr oo)(x^(5))/(5^(x))=

lim_(x rarr oo)x^(3)

lim_(x rarr oo)a^(x)

Let f:rarr R rarr(0,oo) be strictly increasing function such that lim_(x rarr oo)(f(7x))/(f(x))=1 .Then, the value of lim_(x rarr oo)[(f(5x))/(f(x))-1] is equal to

lim_(x rarr oo)e^(-x^(2))

lim_(x rarr oo)e^(-x^(2))

lim_(x rarr oo)e^(-x^(2))

lim_(x rarr oo)e^(-x^(2))

lim_(x rarr oo)(x-1)/(x)

lim_(x rarr oo)(x)/(x+1)

lim_(x rarr oo)(x)/(e^(x))=?
