5x3x or ex

Is it Right? Evaluate the limit, if it exists : lim x-->infinity (5^x-3x)/(e^x+5x^2)? Evaluate the limit, if it exists : lim x-->infinity (5^x-3x)/(e^x+5x^2) lim x-->infinity (5^x-3x)/(e^x+5x^2) => Infinity/Infinity Since it is infinity/infinity , we can use L'Hospital's rule. So: lim...
