Question

Use the log table to estimate the value of log10 8.65.

Answer 1

I think it is 86.5, but that's just me.

Answer 2

Answer:

0.9370

Step-by-step explanation:

The logarithmic table (of base 10) is used like this:

First turn the number in scientific notation, but in this case, the number is small and already in "scientific notation", 8.65.

Take the number 8.65 and divide it, first two numbers first and then all the others, one by one.

Locate 8.6 at the left, then the next number, 5 would be at the top, if you had any other number after the 5 you would look for it in the mean difference part, and then would add the number you get, divided by 1000 to the number you found from 8.6 and 5.
