Step 1: Simplify the expressions inside the brackets.
[2+1]=3
[3+3]=6
The expression is now
6+6×2+45+3⋅5+3
Step 2: Perform the multiplications (following order of operations).
Numerator: 3⋅5=15 → 5+15+3
Denominator: 6×2=12 → 6+12+4
Step 3: Add in the numerator.
5+15=20
20+3=23
Add in the denominator.
6+12=18
18+4=22
The expression simplifies to
2223
Final answer:
\dfrac{23{22}}
