	 		| What is 'Index Law of Multiplication' ? | 
 
	  
	 	| Answer :
 | 
	  
	 		| That the final index of a letter occuring more than once in a product is the sum of the indices of that letter. | 
	  
	 		| In general it can be stated as : | 
	  
	 		    | am 
                  x an = am + n | 
	  
	 		| For example : | 
	 
	  
	 		| a2 x a5 x a7 = a2+5+7 = a14  or  a2b2 x 
			a7b3 |
