As found in the above example, we can find the mantissa for the sequence of digits 534 as 7275. Since there are four significant digits in 5342, in the same row where we found 7275 under the column 2 in the mean difference column, we can find the number 2.
`therefore` The mantissa of the logarithm of 5342 is 7275 + 2 = 7277.
Thus, log 5.342 = 0.7277
Similarly, log 0.05342 = `bar(2)`.7277.
