ok, i don't get this stuff.
X2 x X5 =X7
X^2 = XX
X^5 = XXXXX
So X^7 = XXXXXXX
--------------------------------------------
(this next part i understand how they did this)
(X4)2 = X8
(XXXX)(XXXX) = X^8
--------------------------------------------
(i don't get how they got this)
(XY)3 = X3Y3
(XY)(XY)(XY) = (XXX)(YYY) = X^3y^3
=======================================
