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.
.3 * 18 = 5.4. 18-5.4 = 12.6$
Or
.7 * 18 = 12.6$
13 because you do 18-8 and you get 10 and divide that by 2 and you get 5 then add 5 to 8 and you get 13 and subtract 5 from 18 and you get 13 as well. Hope that helps
I am not sure if you gave all of the information but if you did A because A > B. Did I miss something?
