To solve the given problem, we have to evaluate the expression

[tex]n^2\times7-3[/tex]

at n=3.

First, we compute the square of 3:

[tex]\begin{gathered} 3^2\times7-3, \\ 9\times7-3. \end{gathered}[/tex]

Now, multiplying by 7, we get:

[tex]63-3.[/tex]

Finally, subtracting 3, we get:

[tex]60.[/tex]

Answer:

[tex]60.[/tex]
