\begin{align*}\dfrac{a^3+a^3+a^3}{6}=a^4\end{align*}

What positive value of a satisfies the equation above?

but who ever leaves equations in fractions? however if you isolate the 2 you can also remember that:
any number raised to the power of -1 is the inverse ie 2^-1 = 1/2
so a^3/a^4 =2 therefore a^-1=1/2
