Question

rationalise and simplify
$\sqrt{5 - 2 \div \sqrt{5 + 2 - \sqrt{5 + 2 \div \sqrt{5 - 2} } } }$
​

Answer 1

Step-by-step explanation:

$\sqrt{5 - 2 \sqrt{5 + 2 - \sqrt{5 + 2 \div \sqrt{5 - 2} } } }$

$\sqrt{3 \div \sqrt{7 - \sqrt{7 \div \sqrt{3} } } }$

$\sqrt{3 \div \sqrt{7 - \sqrt{7 \div \sqrt{3} } } }$

$\sqrt{3 \div \sqrt{7 - \sqrt{2.3 \sqrt{3} } } }$

$\sqrt{3 \sqrt{3 - \sqrt{2.3 \times 1.732} } }$

$\sqrt{3 \div \sqrt{7 - \sqrt{3.99} } }$

$\sqrt{3 \div \sqrt{7 - 1.9} }$

$\sqrt{3 \div \sqrt{5.1} }$

$\sqrt{3 \div 2.25}$

$\sqrt{1.3}$
