only issue I can find with it is that for the answer I got it should really have been written as:
01.(y2-x).(y2-102)10 //the 102 is ten sqared
the last x is redundant unless is is supposed to be used, but then x10 should have been x*10 and then the answer is:
01.876.192000
then of course it could have been meant as "x to the 10th power", but the resulting number would not be viable. and as the writer got the squared portion written correctly, there is no doubt that the "10th" would have been notated correctly if that was the intention...
so in conclution, I direct you to the original answer as the conclusive one...
