Use logarithm tables to evaluate and express your answer in the form A×10, where A is a number between 1 and 10 N is an integer.
To use logarithm tables to evaluate a number, we can take the logarithm of the number and then convert it back to its original form.
Let's say we want to evaluate the number 1,000. We can take the logarithm (base 10) of 1,000:
log(1,000) = 3
Then we can express the answer in the form A×10^N:
3 × 10^3
So the answer is 3,000.
