Without using a calculator, order the following numbers in ascending order: \(\left(\frac{1}{7}\right)^2 , (-5)^2 , \pi^2 ,(-1)^2\).
\(\left(\frac{1}{7}\right)^2 \lt (-5)^2 \lt \pi^2 \lt (-1)^2\)
\(\left(\frac{1}{7}\right)^2 \lt (-1)^2\lt \pi^2\lt (-5)^2\)
\( (-1)^2 \lt \left(\frac{1}{7}\right)^2 \lt \pi^2\lt (-5)^2\)
\((-5)^2 \lt (-1)^2 \lt \left(\frac{1}{7}\right)^2 \lt \pi^2\)
