When we say cubic root, it means that the exponent of your divisor is three. You can solve this by counting how many three's are there in a ten. So there are three three's. the other x has an exponent one and therefore is denoted by ∛x. The answer would be x³∛x.
The rate of change is meaning the slope. The slope of A is 8, therefore, the answer would be 7.
hope this helps :)
You just answerd it yourself i think.......
