\underline{\textsf{Given:}}

\mathsf{m-10=\dfrac{1}{m-2}}

\underline{\textsf{To find:}}

\textsf{The value of}

\mathsf{(m-2)^2+\dfrac{1}{(m-2)^2}}

\underline{\textsf{Solution:}}

\textsf{Consider,}

\mathsf{(m-2)^2+\dfrac{1}{(m-2)^2}}

\textsf{Using the identity,}

\boxed{\mathsf{a^2+b^2=(a-b)^2+2ab}}

\mathsf{=(m-2-\dfrac{1}{m-2})^2+2(m-2)\dfrac{1}{m-2}}

\mathsf{=(m-2-(m-10))^2+2(m-2)\dfrac{1}{m-2}}

\mathsf{=(m-2-(m-10))^2+2}

\mathsf{=(m-2-m+10)^2+2}

\mathsf{=(8)^2+2}

\mathsf{=64+2}

\mathsf{=66}

\underline{\textsf{Answer:}}

\textsf{The value of}

\mathsf{(m-2)^2+\dfrac{1}{(m-2)^2}}\;\textsf{is 66}
