Question 12

The diagram shows part of the graph of y=20x13−10x13\displaystyle y = 20x^{\frac{1}{3}} - \frac{10}{x^{\frac{1}{3}}}y=20x31​−x31​10​

The shaded region is enclosed by the curve, the xxx-axis and the lines x=1x = 1x=1 and x=ax = ax=a, where a>1a > 1a>1

A Cartesian graph of the given curve for positive x, with the region between x = 1 and x = a shaded beneath the curve and above the x-axis.

Given that the area of the shaded area is 1650 square units, find the exact value of aaa.
