Welcome back Ngoh — missed you this week.
Step 1: Simplify the expression inside the first parenthesis.
21+41=42+41=42+1=43
Step 2: Simplify the expression inside the second parenthesis.
65−31=65−62=65−2=63=21
Step 3: Multiply the results from Step 1 and Step 2.
43×21=4×23×1=83
The simplified expression is:
\frac{3{8}}
