1 / (a^3 * a^8)   =  a^x

 

1 / (a^11)   = a^x         [remember......1/a^n   = a^(-n)  ]

 

a^(-11)  = a^x

 

So   ...    x  must  =   -11

 

 

cool cool cool

Well......we obviously can't answer "several hundred".......you could upload a pic of what you're working on, or just paste a few problems on one post.......we'll see what we can do.....smiley smiley indecision
