Question

select the correct answer.
which exponential equation is equivalent to this logarithmic equation?
\log x = 4
a. \\ 10^4 = x
b. \\ 10^x = 4
c. \\ e^4 = x
d. \\ e^x = 4

Explanation:

Step1: Recall log definition (base 10)

A logarithm $\log x$ uses base 10: $\log_{10} x = 4$.

Step2: Convert to exponential form

For $\log_b a = c$, $b^c = a$. Substitute $b=10$, $c=4$, $a=x$:
$10^4 = x$

Answer:

A. $10^4 = x$
