Answer 2

Answer:

$by \: rationalising \: the \: factor \: of \: \sqrt{4 + 5 \div \sqrt{4 + 3 \: we \: get \: } }$

$\sqrt{4 + 5 = 9 \: \: then \: \: \sqrt{4 + 3 = 7 } } \\ \: so \: the \: square \: root \: of \: \sqrt{9 = 3 \: is \: the \: answer. \: then \: \sqrt{7 = 3.5 \: comes \: the \: answer.} }$

By this formula , The anwer will come.
