- \frac{34}{27}

Decimal Notation

- 1.25925 \dots

Solution steps

(\frac{2}{3})^{3} - 2 (\frac{2}{3})^{2} - 4 (\frac{2}{3}) + 2

Apply rule:

(a) = a

(\frac{2}{3}) = \frac{2}{3}

= (\frac{2}{3})^{3} - 2 (\frac{2}{3})^{2} - 4 \cdot \frac{2}{3} + 2

(\frac{2}{3})^{3} = \frac{8}{27}

(\frac{2}{3})^{2} = \frac{4}{9}

4 \cdot \frac{2}{3} = \frac{8}{3}

= \frac{8}{27} - 2 \cdot \frac{4}{9} - \frac{8}{3} + 2

\frac{8}{27} - 2 \cdot \frac{4}{9} - \frac{8}{3} + 2 = - \frac{34}{27}

= - \frac{34}{27}

c + (4 - 3 c) - 2 = 0

3 a^{2} + 16 a - 35

9 8 rs - 5 8 rs + 7 8 rs

∣ 3 x + 4 ∣ \geq 13

4 x^{2} - 16
