Explanation

Solution: প্রশ্নে বল হচ্ছে যে,

\sqrt {150}

এবং

\sqrt {54}

এর পার্থক্য কত ? উত্তর অপশনে দেখুন সবগুলোতে

\sqrt 6

আছে, তাই এটা যখন সরল করবেন তখন

\sqrt 6

চিন্তা করবেন। তাই

\sqrt {150}  = \sqrt {25 \times 6}  = 5\sqrt 6

\sqrt {54}  = \sqrt {9 \times 6}  = 3\sqrt 6

________________________________________________ (-)

\sqrt {150}  - \sqrt {54}  = 2\sqrt 6

Shortcut:

\sqrt {150}  - \sqrt {54}  = \sqrt {6 \times {5^2}}  - \sqrt {6 \times {3^2}}  = 5\sqrt 6  - 3\sqrt 6  = 2\sqrt 6
