Convert 4 Expressions from Exponential to Logarithmic Form & 4 from Logarithmic to Exponential Form

As exponential and logarithmic functions both with base b are inverse functions, then b^y=x is equivalent to y=log(base b)x. This is used to convert the following 4 expressions to logarithmic form: b^3=343, 4^(-3)=1/64, e^w=3, and 10^(1/2)=x. Then the following 4 expressions are converted from logarithmic form to exponential form: log(base b)100=2, log(base 8)2=1/3, ln(x)=5, and common log(49)=z.
