The answer is x=25 logx+log4=2 First we use the identity which says that: loga+logb=log(a*b) log(4x)=2 Then we change the number on the right side to a logarythm using a formula: a=log_b(b^a) log(4x)=log100 Now we can skip the logarythm signs because both sides are single logarythms with the same base. The operation is a special case of the logarithm, i. Generally, when we look for ordered pairs for the graph of a function, we usually choose an x -value and then determine its corresponding y -value. log_4 x=3 can be written in exponential form as x=4^3 log_a b=m can be written in exponential form as a^m=b Hence log_4 x=3 can be written in exponential form as x=4^3.
