This is the markscheme for a past a level maths paper im currently doing. The question asks to show the area can be written as p+qln2, but i cant figure out how to get from -(256/3)ln8 to -256ln2. Ive tried switching the 256 and the ln8 to get ln8/3, as that would leave the 256 where it's supposed to be, but ln8/3 dosent equal ln2. Im sure its fairly simple, but I just cant figure out how to get it in the form they want

Thanks in advance :)
