expand (3(3-sqrt(2)))/7

expand

\frac{3 ( 3 - 2 )}{7}

\frac{9}{7} - \frac{3 2}{7}

Decimal Notation

0.67962 \dots

Solution steps

\frac{3 ( 3 - 2 )}{7}

Expand

3 (3 - 2) : 9 - 32

= \frac{9 - 3 2}{7}

Apply the fraction rule:

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

\frac{9 - 3 2}{7} = \frac{9}{7} - \frac{3 2}{7}

= \frac{9}{7} - \frac{3 2}{7}

x^{\frac{2}{3}} (x - 6)

\frac{\frac{d}{d x} ( ( 4 x ^{3} + 7 ) ^{5} )}{( 12 x + 9 ) ^{2}}

\frac{( - 2 s + 6 ) ( - s ^{2} + 6 s + 39 )}{( s ^{2} - 6 s + 25 ) ^{3}}

\frac{1}{( 1 - x ) ^{4}}

e^{2 t} t^{2} U (t - 3)
