Hi there!
Here is the step by step explanation into solving this :
4 × (2² + 5)² ÷ 3 - 1
Start by solving the inside of the parentheses
2² = 2 × 2 = 4
4 + 5 = 9
Distribute the "²" to the whole parentheses
9² = 9 × 9 = 81
4 × 81 ÷ 3 - 1
Do the multiplication, then the division and lastly the subtraction
4 × 81 = 324
324 ÷ 3 = 108
108 - 1 = 107
The answer is : 107
There you go! I really hope this helped, if there's anything just let me know! :)
