SUMMARY
The discussion focuses on evaluating the integral of the function \( (x^2+y^2)^{7/2} \) over the disk defined by \( D: x^2+y^2 \le 16 \) using polar coordinates. The integral is denoted as \( I=\iint_{D}(x^2+y^2)^{7/2}dxdy \). By converting to polar coordinates, the limits are set as \( 0 \le \theta \le 2\pi \) and \( 0 \le \rho \le 4 \). The final evaluation yields \( I = \frac{2^{19}\pi}{9} \).
