Express 45 = x as a logarithmic equation.
log45 = x
log4x = 5
log54 = x
log5x = 4

Option 2nd is correct

Step-by-step explanation:

Using logarithmic rules:

Given that:

Taking log with base 4 to both side we have;

Apply the logarithmic rules we have;

or

Therefore, as a logarithmic equation is:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
