I do not understand ???????????????????
It’s not my answer but I think it’s correct!
Answer:
1
Step-by-step explanation:
We are given the expression
and are asked to find the value of it.
To solve this, we can use the exponent rule of multiplying the exponent inside of the parenthesis with the one outside of the parenthesis.



Anything with an exponent of zero equals 1. Therefore :

SIMPLE math 120+(2x+30)+x=180
150+2x+x=180
150+3x=180
3x=30
x=10
