Answer
$$x=-0.631$$
Work Step by Step
$$3^x-0.5=0$$
$$3^x=0.5$$
- Draw the graph of the function $y= 3^x$
- Draw the graph of the function $y=0.5$
- Trace the point of intersection of the 2 graphs, the $x$ value of which is the answer to the given equation.
Thus, from the graph, as the point of intersection is $(-0.631,0.5)$, we conclude that $$x=-0.631$$
