20%
source= 8/10 is 80% so you take the remaining 20% which is the percent of increase
(24+2)+2=28.
First, you work with the parentheses. (24+2)=26. So now your expression is 26+2. Lastly, you solve the expression. 26+2=28.
So that equation was definitely correct...
When you expand the equation in the bracket you'll find out that you'll get a^6 + 4a^4 + !6a^2 - 4a^4 - 16a^2 -64. then your final result will be a^6 - 64
