Use the MDAS method, solve for those equation first inside the parenthesis or brackets(if there is any).
2 + 3 (4 + 2)² - 5
Solve for 4 + 2 first
2 + 3 (6)² - 5
Get the square of 6
2 + 3 (36) - 5
Multiply 3 and 36
2 + 108 - 5
Now add 2 and 108
110 - 5
Lastly, Subtract the remaining value
105
There you have it
I hope it helps
