    Explanation:

    \begin{aligned}
    = \sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+\sqrt{225}}}}}
    \end{aligned}

    \begin{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}

    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}

    Please improve the website UI and give some functionality like -
    1.when user click over the answers like options there should be a check box , yeah you are right
    2 when wrong answer then a cross apear OOPs !! you did wrong .
    This will be better , because no one want to see the answer every time , just see the question , solve in mind and tick your answer.

    Thanks i hope you will adopt it :)
