In the equation m3 = 5, we identify m is the base, 3 is the exponent, and 5 is the value. A logarithm base b of a positive number x satisfies the following definition. If there is an exponent in the argument of a logarithm, the exponent can be pulled out of the logarithm and multiplied. Determine the exact value of: `log_3root(4)27` Answer. Example 4: Convert log 3 (7) into an expression with base 10. 7.25. Simplify 2log(x) 2 log ( x) by moving 2 2 inside the logarithm. The power property for logarithms states that as long as b ≠ 1, then logbxn = nlogbx. ln e√ = 12 ln.
