Using logarithm tables solve

Question

0.000083÷4

Answer 1

To solve this problem using logarithm tables, we need to first convert the division operation into a subtraction operation by taking the logarithm of the numbers involved.

First, determine the logarithm of each number:
log(0.000083) = -4.082785
log(4) = 0.602060

Now, subtract the logarithms:
-4.082785 - 0.602060 = -4.684845

Finally, convert the result back to a normal number by finding the antilogarithm:
10^-4.684845 = 0.000060368

Therefore, 0.000083 ÷ 4 is approximately 0.000060368.
