We can write logarithms as exponential so the properties of logarithms 
		are related to the rules of exponents.	
	
		Logarithm Properties-		
		If x and y are positive numbers, b>0 and b is not equal to one:		
		     		
		Example		
		 
		
		     
		Example		
		 
		
		              
		Example		
				
		
		We can use these properties to condense an expression involving several log terms into a single log term.		

		Example2		
		Write each of the following as a single logarithm:		
				
		These properties can also be used to solve equations involving only log terms.		

		Example3		
		Solve for t:		
		 
		(The left side is already a single log term so we need to condense 
		the right side to a single log term.)		
				
		So t=200		
		
				
		So
