Answer
$(4^{2}+2)\times3=54$
Work Step by Step
If you evaluate the equation as is, you will find that the solution is 22. This means that solution must be larger. Therefore you can try adding parenthesis around $4^{2}$ and $2$, which will increase the value of the equation. Doing this gets you $(4^{2}+2)\times3$, which is equal to 54, so you have solved the problem.
