Question

If x = 3 , solve for y.

y = 2 * 3 ^ 3
Next, solve the equation using order of operations.
Exponents first.
y =2*[?]

Answer 1

If $x=3$, then $y=2*3^{3}$. Using order of operations, we evaluate the exponent first, then perform the multiplication:

\begin{align*}

y &= 2 * 3^{3} \\

&= 2 * 27 \\

&= 54

\end{align*}

Therefore, $y=54$.
