Math gurus, how is the function in calculated? It's said that we don't need to learn more mathematics in our life, but sometimes it's painful if we don't learn mathematics well. Please answer me two questions 1. How to read in X? 2. How is in X, such as in 10, calculated? In other words, what is the calculation process?

1. Ln is the abbreviation of napierian logarithm or natural logarithm, which is called natural logarithm Ln = LG10 / LGE = 1 / 0.434294481 = 2.302585098

Who knows the specific concept of in mathematical function?

If a ^ x = n (a > 0, and a ≠ 1), then the number x is called the logarithm of n with a as the base. Write it as x = log (a) n. where a is the base of logarithm and N is the true number. And a > O, a ≠ 1, n > 0
The logarithm with base e is called natural logarithm, and log (E) n is denoted as ln n

The function f (x) = in (x + 1) - 1 / X is known. If the zero point of the function is in the interval (n, N + 1) (n ∈ z), the value of n is obtained

Function domain (- 1,0) ∪ (0, + ∞)
f'(x)=1/(x+1) + 1/x²
X ∈ (- 1,0) ∪ (0, + ∞), so f '(x) > 0
F (x) increases monotonically over the domain of definition
