Please tell me this answer with step​

Answer 1

Answer:

$\sqrt{10 + \sqrt{25 + \sqrt{108 + \sqrt{154 + \sqrt{225} } } } } \\ \\ \\ \sqrt{10 + \sqrt{25 + \sqrt{108 + \sqrt{154 + {15} } } } } \\ \\ \\ \\ \sqrt{10 + \sqrt{25 + \sqrt{108 + \sqrt{169} } } } \\ \\ \\ \sqrt{10 + \sqrt{25 + \sqrt{108 + 13} } } \\ \\ \\ \\ \\ \sqrt{10 + \sqrt{25 + \sqrt{121} } } \\ \\ \\ \sqrt{10 + \sqrt{25 + 11} } \\ \\ \\ \sqrt{10 + \sqrt{36} } \\ \\ \sqrt{10 + 6} \\ \\ \sqrt{16} \\ \sqrt{ {4}^{2} } = 4$
