I think if you post less problems per thread, which by the rules is only supposed to be 1, then you will get more help here. I would also suggest seeing this thread for tips on the best way to receive help.

(2) 6^6=46656=4.6656x10^4

(3)a=33 , d=5

$\displaystyle T_7=a+(n-1)d , sub appropriately .$

You know what. I'm just going to close this thread. It is a complete shambles - it contains posts I've moved from a thread where these questions have been double posted, and the OP has made repeated edits to the original post.
