x^{2} = 0.4

x = \frac{2}{5}, x = - \frac{2}{5}

Decimal Notation

x = 0.63245 \dots, x = - 0.63245 \dots

Solution steps

x^{2} = 0.4

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = 0.4, x = - 0.4

0.4 = \frac{2}{5}

- 0.4 = - \frac{2}{5}

x = \frac{2}{5}, x = - \frac{2}{5}

\frac{4}{\frac{4}{5}} - \frac{4}{\frac{5}{4}}

3 x^{2} - 32 x + 20 \geq 0

6 \cdot 3

2 x + 7 \geq 3

4.5 > \frac{- m}{6}
