Using differentials, find the approximate value of each of the following up to 3 places of decimal.
`(i) sqrt(25.3)" "(ii)sqrt(49.5)`
`

Explanation

To find the approximate values of \( \sqrt{25.3} \) and \( \sqrt{49.5} \) using differentials, we will follow these steps:

### Step 1: Define the function and its derivative
Let \( f(x) = \sqrt{x} \). We need to find the derivative \( f'(x) \):
\[ f'(x) = \frac{1}{2\sqrt{x}} \]
