How do you manually calculate antilog?

How do you manually calculate antilog?

Step 1: Subtract the number by the consecutive whole number. In this example the subtraction will be: – 1-0.628=0.372. Step 2: Now find the antilog of the found positive no I.e in this case 0.372. Log4 can be written as 2 to the power 2, but not as 2*2.

How do you find the log value without a table?

Easiest way to find the log of any number without tables

1. log 2 = 0.3010.
2. log 3 = 0.4771.
3. log 7 = 0.8451.
4. log e = 0.693.
5. Learn the above 4 logarithms.
6. log (ab) = log a + log b -> first logarithm identity.
7. log (a/b) = log a – log b -> second logarithm identity.
8. log (a^b) = b loga -> third logarithm identity.

What is the formula of antilog?

The antilog of any number is just the base raised to that number. So antilog10(3.5) = 10(3.5) = 3,162.3. This applies to any base; for example, antilog73 = 73 = 343.

How do you change log to antilog?

How do you convert log to antilog?

1. Note the base of your logarithm.
2. Raise both sides of the equation to that base. This removes the logarithm. E.g., y = log10(9) becomes 10y = 9.
3. Solve the remaining equation.

How do you convert log to antilog?

How do you find the antilog of an example?

If log M = x, then M is called the antilogarithm of x and is written as M = antilog x. For example, if log 39.2 = 1.5933, then antilog 1.5933 = 39.2.

How do you take Antilog and log?

Logarithmic Laws and Properties log b x y = p + q = log b x + log b y. The division of the two numbers is the antilog of the difference of logarithm of the two numbers. The base should be the same for both the numbers. a p = x = b q, and a r = b.

What is the easiest way to find antilog?

Procedure to Find the Antilog of a Number Step 1: Separate the characteristic part and the mantissa part. From the given example, the characteristic part is 2, and the mantissa part is 6452. Step 2: To find a corresponding value of the mantissa part use the antilog table.

How do you calculate antilog and log?

How to calculate column number in antilog table?

Step 1: The first thing to do is to separate the characteristic and the mantissa part. Here, the characteristic part is 2 while the mantissa part is 7531 Step 2: Using the antilog table, find the corresponding value of mantissa. Find the row number that is equivalent to .75 and then choose the column number. The corresponding value is 5662.

How to find the antilog of 1.4265?

Question 2: Find the antilog of 1.4265. Step 1: The first thing to do is to separate the characteristic and the mantissa part. Here, the characteristic part is 1 while the mantissa part is 4265 Step 2: Using the antilog table, find the corresponding value of mantissa. Find the row number that is equivalent to .42 and then choose the column number.

How to find the antilog of a negative number?

Break it into two parts; The part before decimal: 2 (ignore the negative sign) and the part after it: 0.18. Take the the number we got in step in 3 and find the antilog of it with the help of a log book or a calculator: Now add a negative sign to the number we got in step 2 and raise it to the power of 10:

How to find the value of mantissa in antilog table?

Step 1: The first thing to do is to separate the characteristic and the mantissa part. In the above example, the characteristic part is 2 while the mantissa part is 5463. Step 2: Using the antilog table, find the corresponding value of mantissa.
