Evaluate the logarithm. 11. log_(4)64underline ( ) 12. log_(3)1underline ( ) 13 7^log_(7x)underline ( )

11. To evaluate the logarithm , we need to find the power to which 4 must be raised to get 64.We can rewrite 64 as , since .Therefore, .12. To evaluate the logarithm , we need to find the power to which 3 must be raised to get 1.We know that any number raised to the power of 0 is equal to 1.Therefore, .13. To evaluate the expression , we can use the property of logarithms that states .In this case, and .Therefore, .
