Question 7
Let $$
\begin{aligned} x &= \scriptsize \frac{4}{(\sqrt{5} + 1)(\sqrt[4]{5} + 1)(\sqrt[8]{5} + 1)(\sqrt[16]{5} + 1)}. \end{aligned}
$$ Find $(x + 1)^{48}.$
\begin{aligned} x &= \scriptsize \frac{4}{(\sqrt{5} + 1)(\sqrt[4]{5} + 1)(\sqrt[8]{5} + 1)(\sqrt[16]{5} + 1)}. \end{aligned}
$$ Find $(x + 1)^{48}.$
