Solution steps

\frac{2}{3} - 1

Convert element to fraction:

1 = \frac{1 \cdot 3}{3}

= - \frac{1 \cdot 3}{3} + \frac{2}{3}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{- 1 \cdot 3 + 2}{3}

- 1 \cdot 3 + 2 = - 1

= \frac{- 1}{3}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{1}{3}

(x - 23) (x + 23)

(x + i \cdot y)^{4}

(4 - sin (x))^{2}

(4 + sin (θ)) cos (θ)

x^{- 1 - 103} (- 1 - 103)
