Solution: Take the antilogs of both sides of the equation: [H+] = antilog (-7.35) = 10-7.35 = 4.5 x 10-8 Explanation: Because there were two decimal places in the log, the concentration should have two significant figures.

Use a calculator or log table if the log is not a whole number. 106.8=6309573.45. Log expressions are written two ways: log101,268 = x. or. 10x= 1,268. x = 3.10. Antilogs. When you raise a base to a log you get an antilog. 104= 10,000. Antilog expressions are written two ways: Antilog103.2 = x. or. 103.2= x. x = 1584.89. Scientific notation

log(x) in R and SAS, LN(x) in SPSS and EXCEL, and either . ln(x) or . log(x) in STATA. On calculators, the button to calculate the natural log of a number is . ln. To antilog (cancel out) natural logs, we use the exponential function. This is written as . exp(x) in R, SAS and STATA, and . EXP(x) in SPSS and EXCEL. In calculators, it is given as ...

3. Take the antilog of the result of step 2. This will again be the geometric mean. To do this on the calculator, key the data value and press the "log" key. Then press "+" and repeat for all values. After the last logarithm is entered, press "=" to get the sum. Divide by the number of values that were added.
