Szczegółowe wyjaśnienie:
[tex]\frac{8^{20}- 2 \times 4^{20} }{2^{20} \times 4^{10}} = \frac{(2^{3})^{20} - 2 \times (2^{2})^{20}}{2^{20} \times (2^{2})^{10}} = \frac{2^{60} - 2 \times 2^{40}}{2^{20} \times 2^{20}} = \frac{2^{60} - 2^{41}}{2^{40}} = \frac{2^{40}(2^{20} - 2)}{2^{40}} = 2^{20} - 2[/tex]
