\end{aligned} 16
 8
 6
 4
Answer And Explanation
Answer: Option D
Explanation:
\begin{aligned}
= \sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+\sqrt{225}}}}}
\end{aligned}
\begin{aligned}
=\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+15}}}}
\end{aligned}
\begin{aligned}
=\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+15}}}}
\end{aligned}
\begin{aligned}
=\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{169}}}}
\end{aligned}
\begin{aligned}
=\sqrt{10+\sqrt{25+\sqrt{108+13}}}
\end{aligned}
\begin{aligned}
=\sqrt{10+\sqrt{25+\sqrt{121}}}
\end{aligned}
\begin{aligned}
=\sqrt{10+\sqrt{25+11}}
\end{aligned}
\begin{aligned}
=\sqrt{10+\sqrt{36}}
\end{aligned}
\begin{aligned}
=\sqrt{10+6}
\end{aligned}
\begin{aligned}
=\sqrt{16} = 4
\end{aligned}

7. \begin{aligned}
\sqrt{41  \sqrt{21 + \sqrt{19  \sqrt{9}}}}
\end{aligned} 4
 26
 16
 6
Answer And Explanation
Answer: Option D
Explanation:
\begin{aligned}
= \sqrt{41  \sqrt{21 + \sqrt{19  3}}}
\end{aligned}
\begin{aligned}
= \sqrt{41  \sqrt{21 + \sqrt{16}}}
\end{aligned}
\begin{aligned}
= \sqrt{41  \sqrt{21 + 4}}
\end{aligned}
\begin{aligned}
= \sqrt{41  \sqrt{25}}
\end{aligned}
\begin{aligned}
= \sqrt{41  \sqrt{25}}
\end{aligned}
\begin{aligned}
= \sqrt{41  5}
\end{aligned}
\begin{aligned}
= \sqrt{36} = 6
\end{aligned}
