Question
Parenthesise the following numeric expressions:$$\begin{aligned}& 2^{\wedge} 3^{\star} 4 \\& 2 * 3+4 * 5 \\& 2+3 * 4 \wedge 5\end{aligned}$$
Step 1
According to the order of operations, we should perform the exponentiation first. So, we can rewrite it as $(2^3)^{\star} 4$. Then, we perform the star operation, which is exponentiation, so we have $8^{\star} 4$. Show more…
