i know there are some identities when it comes to horizontal asymptotes
when it is
lim (1/4)^x
x-->infinity
is there an identity for that one?
also while doing the limits to infinity if you have
5^x is this the same as e^x ?

thanks
 
(14)x=1x4x=14x\displaystyle \left(\frac{1}{4}\right)^x = \frac{1^x}{4^x} = \frac{1}{4^x}

now, what happens to the value of 14x\displaystyle \frac{1}{4^x} as x\displaystyle x\to\infty ?
