expand (81(13^{15}-1))/(13^{15)*2}

expand

\frac{81 ( 1 3 ^{15} - 1 )}{1 3 ^{15} \cdot 2}

\frac{81}{2} - \frac{81}{1 3 ^{15} \cdot 2}

Decimal Notation

40.5

Solution steps

\frac{81 ( 1 3 ^{15} - 1 )}{1 3 ^{15} \cdot 2}

Expand

81 (1 3^{15} - 1) : 1 3^{15} \cdot 81 - 81

= \frac{1 3 ^{15} \cdot 81 - 81}{1 3 ^{15} \cdot 2}

Apply the fraction rule:

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

\frac{1 3 ^{15} \cdot 81 - 81}{1 3 ^{15} \cdot 2} = \frac{1 3 ^{15} \cdot 81}{1 3 ^{15} \cdot 2} - \frac{81}{1 3 ^{15} \cdot 2}

= \frac{1 3 ^{15} \cdot 81}{1 3 ^{15} \cdot 2} - \frac{81}{1 3 ^{15} \cdot 2}

Cancel

\frac{1 3 ^{15} \cdot 81}{1 3 ^{15} \cdot 2} : \frac{81}{2}

= \frac{81}{2} - \frac{81}{1 3 ^{15} \cdot 2}

2 (e^{2} - 3)

\frac{1}{( x ^{2} + 1 ) ( x + 1 ) ^{2}}

(- 2 a^{3})^{2}

\frac{( 4 x - 11 )}{( 2 x ^{2} + 7 x - 4 ) d x}

\frac{( s ( 20 + s ^{2} ) ( 37 + 36 s ) )}{10 ( s + 1 )}
