\underline{\textbf{Given:}}

\mathsf{(i)\;A=\{x|\;x{\in}N,\;x^2-5x+6=0\}}

\mathsf{(ii)\;B=\{x|x=n^2\;n{\in}N,\;n&lt;7\}}

\underline{\textbf{To find:}}

\textsf{Roster form of the given sets}

\underline{\textbf{Solution:}}

\underline{\textbf{Roster form:}}

\textsf{In this form,each element of the set is listed}

\textsf{and sepated by commas}

\mathsf{(i)\;A=\{x|\;x{\in}N,\;x^2-5x+6=0\}}

\mathsf{A=\{x|\;x{\in}N,\;(x-2)(x-3)=0\}}

\mathsf{A=\{x|\;x{\in}N,\;x=2,3\}}

\mathsf{A=\{2,3\}}

\mathsf{(ii)\;B=\{x|x=n^2,\;\;n{\in}N,\;n&lt;7\}}

\mathsf{B=\{x|x=1^2,2^2,3^2,4^2,5^2,6^2\}}

\mathsf{B=\{1,4,9,16,25,36\}}
