Here's how to evaluate the expressions using logarithm tables:
a) Evaluate 0.02340.618×9.01
Let X=0.02340.618×9.01.
Using the properties of logarithms, logX=log(0.618)+log(9.01)−log(0.0234).
We will use a 4-figure logarithm table.
| Number | Characteristic | Mantissa | Logarithm (Char + Mantissa) |
| :-------- | :------------- | :------- | :-------------------------- |
| $0.618
