simplify a[13]+a[7]*a[20]-a 13/100 a[2]

simplify

a [13] + a [7] \cdot a [20] - a \frac{13}{100} a [2]

13 a + \frac{6987}{50} a^{2}

Solution steps

a (13) + a (7) a (20) - a \frac{13}{100} a (2)

Simplify

a (13) + a (7) a (20) - a \frac{13}{100} a (2) : a \cdot 13 + a \cdot 7 a \cdot 20 - a \frac{13}{100} a \cdot 2

= a \cdot 13 + a \cdot 7 a \cdot 20 - a \frac{13}{100} a \cdot 2

Factor out common term

aa : aa (7 \cdot 20 - \frac{13}{100} \cdot 2)

= a \cdot 13 + aa (7 \cdot 20 - \frac{13}{100} \cdot 2)

Simplify

aa (7 \cdot 20 - \frac{13}{100} \cdot 2) : a^{2} \frac{6987}{50}

= a \cdot 13 + a^{2} \frac{6987}{50}

= 13 a + \frac{6987}{50} a^{2}

\frac{( x ^{2} - y ^{2} )}{( x - y )}

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

\frac{14}{( x ^{2} - 4 )} - \frac{( 6 - x )}{( x + 2 )}

(2 x)^{2} (x - x^{2}) - 4 x (- x^{3} + x^{2} - 5)

x^{2} + \frac{1}{7} x + \frac{1}{7}
