Using differentials, what is the approximate value of √(16.16)?

C. 4.02

Step 1: Identify the concept: differential approximation. Step 2: Use dy≈f'(a)dx near a known value. Calculation gives approximately 4.02. Step 3: Exam tip: For small changes, use derivative approximation.

Step 1: अवधारणा differential approximation है। Step 2: Near known value पर dy≈f'(a)dx लगाते हैं। Calculation से approx 4.02 आता है। Step 3: याद रखें: छोटे change के लिए derivative approximation use करें।
