To evaluate the given question, we begin by solving for the figures in the bracket. After this is done, the figure obtained is then raised to the power of three or multiplied three times.
(5/7)
= 0.714285.....
The figure obtained is then raised to the power of three, thus;
(0.714285)^3
=0.36443148...
The value obtained here is a continuous or repeating figure so it continues to infinity.
