Question

Calcule a soma da P.G infinita, em que A1= 40 e A2=24

Answer 1

$> resolucao \\ \\ \\ \\ q = \frac{a2}{a1} \\ \\ q = \frac{24}{40} \\ \\ q = \frac{3}{5} \\ \\ > > > > > > \\ \\ \\s = \frac{a1}{1 - q} \\ \\ s = \frac{40}{ 1 - \frac{3}{5} } \\ \\ s = \frac{40}{ \frac{2}{5} } \\ \\ s = 40 \times \frac{5}{2} \\ \\ s = \frac{200}{2} \\ \\ s = 100 \\ \\ \\ > > > > >$
