Answer
(0, 1.6)
Work Step by Step
This question asks for a graph to solve the inequality. Thus, I shall be using Desmos to solve these inequalities with the zeros of the function stated in the graph.
Given $5x^4 < 8x^3$
$5x^4 - 8x^3 < 0$
In the graph below, the zeros are at x= 0, 1.6
From (0, 1.6), the graph is below 0.
Thus the solution is $(0, 1.6)$
