​

Answer 1

Step-by-step explanation:

$\sqrt{43 + \sqrt{32 + \sqrt{18 - \sqrt{4 } } } } \\ \sqrt{43 + \sqrt{32 + \sqrt{18 - \sqrt{2 \times 2} } } } \\ \sqrt{43 + \sqrt{32 + \sqrt{18 - 2} } } \\ \sqrt{43 + \sqrt{32 + \sqrt{16} } } \\ \sqrt{43 + \sqrt{32 + \sqrt{4 \times 4} } } \\ \sqrt{43 + \sqrt{32 + 4} } \\ \sqrt{43 + \sqrt{36} } \\ \sqrt{43 + \sqrt{6 \times 6} } \\ \sqrt{43 + 6} \\ \sqrt{49} \\ \sqrt{7 \times 7} \\ 7$
