ln 5
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! the natural log of (5) is equal to LN(5).
LN is the natural log function button on your calculator.
you should have a LOG function key and an LN function key.
LN is to find the natural log which is the log to the base of e.
LOG is to find the log to the base of 10.
LN(x) is defined as:
LN(x) = y if and only if e^y = x
This is equivalent to the following statement.
log of x to the base of e is equal to y if and only if e raised to the power of y is equal to x.
LOG(x) is defined as:
LOG(x) = y if and only if 10^y = x.
This is equivalent to the following statement.
log of x to the base of 10 is equal to y if and only if 10 raised to the power of y is equal to x.
e is a constant which is equal to 2.718281828.....
