Use logarithms to evaluate sqrt(56.86) x 12.3450.415

Here are the solutions to the questions:

Question 1:
Use logarithms to evaluate:

$$\frac{\sqrt{56.86} \times 12.345}{0.415}$$

Step 1: Let $X = \frac{\sqrt{56.86} \times 12.345}{0.415}$.
Take the logarithm of both sides:

$$\log X = \log\left(\frac{\sqrt{56.86} \times 12.345}{0.415}\right)$$
