Question

1/3 + 1/9 + 1/27+1/81 + 1/243+ 1/729.

Answer 1

\(\frac{1}{3}+\frac{1}{9}+\frac{1}{27}+\frac{1}{81}+\frac{1}{243}+\frac{1}{729}\)

\(=\frac{243}{729}+\frac{81}{729}+\frac{27}{729}+\frac{3}{729}\)

\(=\frac{243+81+27+3}{729}=\frac{354}{729}\)

Answer 2

1/3 + 1/9 + 1/27 + 1/81 + 1/243 +1/729 = 354/729

Answer 3

1/729 x ( 243 + 81 + 27 + 9 + 3 + 1) = 364/729
