1.
Each line is also the powers (exponents) of :

= (the second line is "" and "")
= (the third line is "", "", "")
= (the fourth line is "", "", "","") ...this line is your line
so, will be:






2.


= (the first line is just a "")
= (the second line is "" and "")
= (the third line is "", "", "")
= (the fourth line is "", "", "","")

= ...the 5th line

= ...the 6th line-your line
