Question

The value of $\sqrt{144} + \sqrt{0.0169} - \sqrt{4.41} =$

• A. 11.2
• B. 14.23
• C. 15.4
• D. 10.03

Answer 1

Answer:

D. 10.03

The value of the given expression is 10.03.

$\sqrt{144} + \sqrt{0.0169} - \sqrt{4.41}$

1. Find the value of each square root:

   • $\sqrt{144} = 12$ (since $12 \times 12 = 144$)

   • $\sqrt{0.0169} = 0.13$ (since $0.13 \times 0.13 = 0.0169$)

   • $\sqrt{4.41} = 2.1$ (since $2.1 \times 2.1 = 4.41$)

2. Substitute these values back into the expression:
   $12 + 0.13 - 2.1$

3. Perform the addition and subtraction:

   • First, add: $12 + 0.13 = 12.13$

   • Next, subtract: $12.13 - 2.1 = \mathbf{10.03}$
