Question

Simplify (1/8)+(1/8)²+(1/8)³+(1/8)⁴+(1/8)^5

Answer 1

$\frac{1}{8} + { \frac{1}{8} }^{2} + { \frac{1}{8} }^{3} + { \frac{1}{8} }^{4} + { \frac{1}{8} }^{5}$

$\frac{1}{8} + \frac{1}{64} + \frac{1}{512} + \frac{1}{4096} + \frac{1}{32768}$

$\frac{4096 + 512 + 64 + 8 + 1}{32768}$

$\frac{4681}{32768}$

$= 0.142853$
