2015年11月11日 · It is exactly x. You are looking for a number that is the exponent of the base of ln which gives us the integrand, e^x; so: the base of ln is e; the number you need to be the exponent of this base to get e^x is.....exactly x!!! so: ln(e^x)=log_e(e^x)=x

I have a hard time understanding why $\\ln e=1$ Can someone explain to me why the natural logarithm of e is exactly equal to the first nonzero but positive integer?

2016年8月4日 · ln(e^3)=3 By definition, log_a(x) is the value such that a^(log_a(x)) = x From this, it should be clear that for any valid a and b, log_a(a^b)=b, as log_a(a^b) is the value such that a^(log_a(a^b))=a^b. As the natural logarithm ln is just another way of writing the base-e logarithm log_e, we have ln(e^3) = log_e(e^3) = 3

2016年7月25日 · ln(ln e^(e^10)) = 10 As functions of Real numbers, ln(x) and e^x are inverses of one another. So: ln(ln e^(e^10))=ln(e^10) = 10

2018年4月27日 · 2 ln(x) is asking e to the power of what is x In this case, e to the power of 2 is e^2 thus, ln(e^2)=2 Another way is using the property of logarithms that says ln(a^b)=b*ln(a) In this case, a=e and b=2 Thus, ln(e^2)=2*ln(e)=2*1=2

2015年2月17日 · The result should be: x=-1 Consider that from the definition of logarithm: log_ab=x =>a^x=b and that log_e is ln; So you get: ln1=0 because e^0=1 lne=1 because e^1=e in your equation.: 0-1=x x=-1

2015年10月10日 · The function e^x:RR->(0, oo) and ln:(0, oo)->RR are inverse functions of one another. So for any x in RR, ln(e^x) = x and for any x in (0, oo), e^ln(x) = x The natural logarithm ln(x) is defined such that e^ln(x) = x So what about ln(e^x) ? By the definition of ln, we have e^(ln(e^x)) = e^x Since e^x is a one-one function, we can deduce that the exponents ln(e^x) …
