Question

Use the change of base formula to evaluate log3(73).

Answer 1

d.3.905

Explanation:

Answer 2

The change of base formula allows you to write a logarithm in terms of logarithms with another base. It follows this pattern,


`log_(a)x = ( log_(b)x )/(log_(b)a )`

where a≠1 and b≠1

Assigning the base to be 7,


`log_(3)73 = ( log_(7)73 )/(log_(7)3 )=3.9`
