Asked by maham237 @ in Mathematics viewed by 274 People

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

Answered by maham237 @


Answer:

Option 2nd is correct

\log_4 x = 5

Step-by-step explanation:

Using logarithmic rules:

\log_b b^x = x

Given that:

4^5 = x

Taking log with base 4 to both side we have;

\log_4 4^5 = \log_4 x

Apply the logarithmic rules we have;

5 = \log_4 x

or

\log_4 x = 5

Therefore, 4^5 = x as a logarithmic equation is: \log_4 x = 5
