I suppose you mean log21 - the logarithm of 1, to the base 2. The logarithm of 1 (in any base) is zero, since x0 = 1 for any "x".
Rational.
1: Calculate the square root, then calculate its square root; OR 2: Take the logarithm of the number, divide it by 4 then take the antilog.
The logarithm base 4 of 16 is asking the question "4 raised to what power equals 16?" In this case, 4 squared is equal to 16, so the answer is 2. Therefore, log base 4 of 16 is equal to 2.
Multiply the base by square root of 10 to the 4th power then divide by 2! (factorial) times 10!
The base 10 logarithm of 0.01 is -2.
log 2 = 0.30102999566398119521373889472449 for base 10 logarithms

Logarithms can be taken to any base. Common logarithms are logarithms taken to base 10; it is sometimes abbreviated to lg. Natural logarithms are logarithms taken to base e (= 2.71828....); it is usually abbreviated to ln.
-1/(2*x2)
Take its logarithm, divide that by 2 and take the antilog of your answer....
Assuming you mean 'logarithm to the base 'e' ( natural logarithm. On the calculator its symbol is 'ln'. Hence ;ln 2 = 0.69314718....
Yes. Logarithms to the base 10 are called common logarithms, and 2 is the correct common logarithm for 100.
Rational.
Especially if the 2 is written as a subscript, it means the base-2 logarithm.
If a^x = n, where a is a positive real number other than 1 and x is a rational number then logarithm is defined as, logarithm of n to the base a is x. Then is written as log n base a = x.
A number for which a given logarithm stands is the result that the logarithm function yields when applied to a specific base and value. For example, in the equation log(base 2) 8 = 3, the number for which the logarithm stands is 8.
