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 $(0, 1.6)$
