What is a natural log of x?
The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately equal to 2.718281828459. The natural logarithm of x is generally written as ln x, loge x, or sometimes, if the base e is implicit, simply log x.
What is the base of ln x?
ln(x) means the base e logarithm; it can, also be written as loge(x) . ln(x) tells you what power you must raise e to obtain the number x.
How do you make a logarithmic graph?

What is the formula for natural log?
Product Rule: The logarithm of a product of two numbers is the sum of the logarithms of the individual numbers.
What are the rules of natural log?
– Logarithm to the base āeā is called natural logarithms. The constant e is approximated as 2.7183. Natural logarithms are expressed as ln x, which is the same as log e – The logarithmic value of a negative number is imaginary. – The logarithm of 1 to any finite non-zero base is zero. a 0 =1 ā¹ log a 1 = 0.
