Question 30306
6^3a+2 multiplied by 6^2-2a
---------------------------
           6^a+5

=[(6)^(3a+2)]X[(6)^(2-2a)]X[1/(6)^(a+5)]     (using (ab)/c = (ab)X(1/c) )
={(6)^[(3a+2)+(2-2a)]}X[1/(6)^(a+5)]   
(when quantities of the same base are multiplied 
write the base and add the powers)
=(6)^[3a-2a+2+2]X(6)^[-(a+5)]    ( Using the rule (1/a^m) = (a)^(-m))
=(6)^(a+4) X (6)[-(a+5)]    
=(6)^[(a+4)-(a+5)] 
(when quantities of the same base are multiplied 
write the base and add the powers)
=(6)^(a+4-a-5)
=(6)^(4-5)
=(6)^(-1)
=1/(6)^1
=1/6
