Question

Calcule o valor do número X sabendo que

X=1/2+1/2^(2)+1/2^(3)+1/2^(4)+1/2^(5)

Answer 1

$x= \frac{1}{2} + ( \frac{1}{2})^{2} + ( \frac{1}{2})^{3} + ( \frac{1}{2})^{4} + ( \frac{1}{2})^{5}$
$x= \frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \frac{1}{16} + \frac{1}{32}$
x= $\frac{16+8+4+2+1}{32} = \frac{31}{32}$
