Remember to wrap math in $$...$$ or $...$ to ensure proper formatting.
2 \times 3 $$2 \times 3$$
2^{34} $$2^{34}$$
a_{i-1} $$a_{i-1}$$
\frac{2}{3} $$\frac{2}{3}$$
\sqrt{2} $$\sqrt{2}$$
\sum_{i=1}^3 $$\sum_{i=1}^3$$
\sin \theta $$\sin \theta$$
\boxed{123} $$\boxed{123}$$

Sort by:

Multiply numerator and denominator by 5^(1/16) - 1, and apply a^2 - b^2 = (a-b)(a+b) a couple of times, you get

x = 4(5^(1/16 - 1)/(5 - 1) = 5^(1/16) - 1

x + 1 = 5^(1/16)

(x + 1)^48 = 5^(48/16) = 5^3 = 125
