计算:
(1) $[ -(-\frac{1}{5})^2 - \frac{1}{5^2} ] × [ (-2)^2 - ( \frac{7}{15} - \frac{1}{30} ) × (-12) × (-5) ]$;
(2) $[ -1^4 - (-3)^2 ] × [ ( 4\frac{1}{5} - 3\frac{1}{2} + 1\frac{3}{4} ) ÷ 7^2 + (-0.07)^2 ÷ (0.01)^2 ]$;
(3) $( -39\frac{6}{7} ) ÷ 3 × \frac{7}{31} + \frac{1}{5} × ( -\frac{1}{85} + \frac{8}{17} + \frac{1}{5} ) × 17 - ( \frac{4}{5} )^2$;
(4) $(-5)^3 × \frac{3}{13} + (-5)^3 × ( -\frac{2}{13} ) - 5^3 × \frac{1}{13} + 0.125 × ( -\frac{10}{13} ) × (-8)$。
