Answer:
1. (80 +220) = 10²
Add Within Parenthesis
300 = 10²
Expand The Squared Number
300 = 100
2. (2 + 32) x 5
Add Within Parenthesis
34 x 5
Multiply The Given
170
3. 2 x [(4 x 52) = 10]
Multiply Within Parenthesis
2 x [208 = 10]
Multiply Outside
416 = 10
4. (36 - 6) + (3 x 4) = 2²
Solve Both Parenthesis
30 + 12 = 2²
Add The Given
42 = 2²
Expand The Number
42 = 4
