Simplify the following:

$$72 - 52 + 32 \div 2 \times 32 \div 8$$​

Correct option is D

Given:

​$$72 - 52 + 32 \div 2 \times 32 \div 8$$

Concept Used:

​$$\begin{array}{|c|c|} \hline \textbf{Operation preference wise} & \textbf{Symbol} \\\hline Brackets &[],{}, () \\ \hline Orders, of & (power), √ (root) , of \\ \hline Division& ÷ \\ \hline Multiplication & × \\ \hline Addition & + \\ \hline Subtraction & - \\\hline \end{array}$$

Solution:

72 − 52 + 32 ÷ 2 × 32 ÷ 8 

= 72 − 52 + 16 × 4

= 72 − 52 + 64

= 20 + 64

= 84

Thus, correct answer is (d) 84
