1. The problem asks to select all the squares containing perfect squares and order them from least to greatest. 2. Let's evaluate each expression to identify which are perfect squares: - $\int_1^5 x \, dx = \left[\frac{x^2}{2}\right]_1^5 = \frac{25}{2} - \frac{1}{2} = 12$ (not a perfect square) - $\sum_{i=1}^6 i = 1+2+3+4+5+6 = 21$ (not a perfect square) - $\sqrt{2} \approx 1.414$ (not a perfect square) - $7! = 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 5040$ (not a perfect square) - $\frac{6\pi}{3} = 2\pi \approx 6.283$ (not a perfect square) - $\infty$ (infinity, not a number, so not a perfect square) - $e^5 \approx 148.413$ (not a perfect square) - $\frac{5}{10} = 0.5$ (not a perfect square) - $\log_4(19) \approx 2.15$ (not a perfect square) 3. None of these expressions evaluate to perfect squares. 4. Therefore, there are no squares to select in order from least to greatest. Final answer: No perfect squares found among the given expressions.
