– List the given data

The given expression to be simplified is $3 + (21 \div 7) \times 8 \div 4$

– Simplify

$3 + (21 \div 7) \times 8 \div 4$ (Given expression)

$3 + (\frac{21}{7}) \times 8 \div 4$ (Evaluating the expression in the brackets)

$3 + 3 \times 8 \div 4$ (Simplify)

$3 + 3 \times \frac{8}{4}$ (Performing the division)

$3 + 3 \times 2$ (Simplify)

$3 + 6$ (Performing the multiplication)

$9$ (Performing the addition)

So, 9 is the required simplified value.
