(1-7/2)(1/2-4/5)-3/5:(-2/5+2/3)
$\frac{3v-1}{7v^2-58-45}$ / $\frac{3v-1}{7^2-2v-5}$
(1-7/2)(1/2-4/5)-3/5/(-2/5+2/3)
$\frac{3v-1}{7v^2-58-45}$ / $\frac{3v-1}{7^2-58-45}$
(1-7/2)(1/2-4/5)-3/5:(-2/5+2/3)=
$\sqrt{3}$ - $\sqrt{15}$ + $\sqrt{1}$ $\sqrt{5}$
using de moivre theorem prove that (1+i√3)^8 + (1+i√3)^8 = 32
