simplify-2*2/5

simplify

- 2 \cdot \frac{2}{5}

- \frac{4}{5}

Solution steps

- 2 \cdot \frac{2}{5}

Convert element to fraction:

2 = \frac{2}{1}

= - \frac{2}{1} \cdot \frac{2}{5}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

\frac{2}{1} \cdot \frac{2}{5} = \frac{2 \cdot 2}{1 \cdot 5}

= - \frac{2 \cdot 2}{1 \cdot 5}

Multiply the numbers:

2 \cdot 2 = 4

= - \frac{4}{1 \cdot 5}

Multiply the numbers:

1 \cdot 5 = 5

= - \frac{4}{5}

6 a^{x + 1} + 8 a^{x + 1}

(1 - sin (x)) \cdot (1 + sin (x))

- x^{3} + 9 x^{2} - 27 x + 27

\frac{7}{3} + \frac{11}{5}

18 a^{2} - 5400 - 360 a
