simplify: which value is an irrational number.
Explanation:(a) the perimeter of the square whose side length is
[tex]\sqrt{8}[/tex]
the perimeter of the square is
[tex]\begin{gathered} 4a \\ =4\sqrt{8} \\ =4\sqrt{4*2} \\ 4*2\sqrt{2} \\ 8\sqrt{2} \end{gathered}[/tex]
we know that
[tex]\sqrt{2}[/tex]
is an irrational number hence the perimeter of the square will also irrational .
