Find the simplest value of \[ 2\sqrt{50} + \sqrt{18} - \sqrt{72} \] (given \( \sqrt{2} = 1.414 \)).

নিম্নলিখিত রাশিটির সরলতম মান নির্ণয় করো: \[ 2\sqrt{50} + \sqrt{18} - \sqrt{72} \] (যেখানে \( \sqrt{2} = 1.414 \)).

Simplify each radical:

\[ \sqrt{50} = \sqrt{25 \times 2} = 5\sqrt{2} \]

\[ \sqrt{18} = \sqrt{9 \times 2} = 3\sqrt{2} \]

\[ \sqrt{72} = \sqrt{36 \times 2} = 6\sqrt{2} \]

Now substitute:

\[ 2(5\sqrt{2}) + 3\sqrt{2} - 6\sqrt{2} \]

\[ = 10\sqrt{2} + 3\sqrt{2} - 6\sqrt{2} \]

\[ = 7\sqrt{2} \]

Using \( \sqrt{2} = 1.414 \):

\[ 7 \times 1.414 = 9.898 \]

Correct Answer: Option A — \( 9.898 \)
