Solution steps

x^{2} - 2 \geq 0

Move

2

to the right side

x^{2} \geq 2

For

u^{n} \geq a

, if

n

is even then

x \leq - 2 or x \geq 2

\frac{2 ^{3}}{2 ^{8}}

\frac{x ^{- 8} y ^{6} z ^{9}}{x y ^{7} z ^{3}}

- \frac{1}{( \frac{1}{9} ) ^{\frac{3}{2}}}

6 (3 x + 1)^{2} - 9 = 3

(\frac{4 x ^{4} y ^{2}}{6 x y})^{2}
