Problem 001
সরল করো:
[tex]\sqrt {32} - 2\sqrt {18} + 5\sqrt 2 + {2^{\frac{3}{2}}}[/tex]
Solution:
[tex]\begin{array}{l}
= \sqrt {16 \times 2} - 2\sqrt {9 \times 2} + 5\sqrt 2 + \sqrt {4 \times 2} \\
= 4\sqrt 2 - 2 \times 3\sqrt 2 + 5\sqrt 2 + 2\sqrt 2 \\
= 11\sqrt 2 - 6\sqrt 2 \\
= 5\sqrt 2
\end{array}[/tex]
