The product of all the values of \(\bigl(\sqrt{3} - i\bigr)^{25}\) is ?
The number of common roots among the 12th and 30th roots of unity is ?
∫ √(2x2 - 5x + 2) dx = ∫ (41/60) dx,
and
-1/2 > α > 0, then α = ?
If \( x \) and \( y \) are two positive real numbers such that \( x + iy = \frac{13\sqrt{5} + 12i}{(2 - 3i)(3 + 2i)} \), then \( 13y - 26x = \):
