Math Olympiad Question

In this Maths Olympiad question we are given a tricky Exponential Equation which is has the nature of a Quadratic Equation. We start by transforming the right hand side to an index expression with base four. After that, we divide each term by this expression to get a Quadratic Equation in terms of (3/2). ‪@EndzeMathsSolutions-mp1wn‬
