Answer 1

\(\dfrac{2.4+2.4.8+4.8.16+8.16.32}{3.4+2.6.8+4.12.16+8.24.32}\)

=\(\dfrac{2.4+2.4.8+4.8.2.8+8.8.2.8.4}{3.4+2.2.3.2.4+4.3.4.16+2.4.3.8.8.4}\)

=\(\dfrac{2.4\left(1+8+8.8+8.8.8\right)}{3.4\left(1+8+4.16+2.4.8.8\right)}\)

=\(\dfrac{2.4\left(1+8+64+8.8.8\right)}{3.4\left(1+8+64+8.8.8\right)}\)

=\(\dfrac{2}{3}\)
