What is the easiest way to find the log of a number?
Below I have mentioned some useful ways to find the logarithm of numbers :
- log 2 = 0.3010.
- log 3 = 0.4771.
- log 7 = 0.8451.
- log e = 0.693.
- Learn the above 4 logarithms.
- log (ab) = log a + log b -> first logarithm identity.
- log (a/b) = log a – log b -> second logarithm identity.
- log (a^b) = b loga -> third logarithm identity.
How do you do simple logarithms?
logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.
How do you find the log of a fraction?
Correct answer: The logarithm of a fraction is equal to the logarithm of the numerator minus the logarithm of the denominator.
How do you find the log method?
Look up the logarithms of the two numbers you want to multiply. Use the method above to find the logarithms. For example, if you want to multiply 15.27 and 48.54, you would find the log of 15.27 to be 1.1838 and the log of 48.54 to be 1.6861. Add the two logarithms to find the logarithm of the solution.

How to calculate log 2(8) in calculator?
For example, in order to calculate log 2 (8) in calculator, we need to change the base to 10: The base b real logarithm of x when x<=0 is undefined when x is negative or equal to zero: The base b logarithm of zero is undefined: The limit of the base b logarithm of x, when x approaches zero, is minus infinity:
What is the formula for calculating loglog b(x × y)?
log b ( x × y) = log b ( x) + log b ( y)
How do you find the value of a logarithm?
The most common type of logarithm table is used is log base 10. Step 2: Identify the characteristic part and mantissa part of the given number. For example, if you want to find the value of log 10 (15.27), first separate the characteristic part and the mantissa part. Step 3: Use a common log table.
What is the common log of a number?
The log function with base 10 is called the common logarithmic function and it is denoted by log 10 or simply log. The log function to the base e is called the natural logarithmic function and it is denoted by log e. To find the logarithm of a number, we can use the logarithm table instead of using a mere calculation.
