Steps to solve the sixth multiple-choice question of liberal arts mathematics in Liaoning college entrance examination in 2009
Because the logarithm is an increasing function, ㏒2(3) is less than ㏒2(4)=2, so 2+㏒2(3) is less than 4, so
F(2+㏒2(3))=f(3+㏒2(3), because 3+㏒2(3) is greater than 4, so it is brought into that exponential equation, which is equal to.
( 1/2)? Multiply by (1/3), so the answer is A( 1/24).
