Rewrite [tex]$2^x=128$[/tex] as a logarithmic equation.

A. [tex]\log _x 128=2[/tex]
B. [tex]\log _2 x=128[/tex]
C. [tex]\log _2 128=x[/tex]
D. [tex]\log _{128} x=2[/tex]

Answer :

We start with the exponential equation
$$
2^x = 128.
$$

To rewrite this equation in logarithmic form, we take the logarithm with base 2 of both sides of the equation. Doing so, we use the property that if
$$
a^b = c,
$$
then
$$
b = \log_a{c}.
$$

Thus, for our equation we have:
$$
x = \log_2{128}.
$$

This means that the logarithmic form of the equation is:
$$
\log_2{128} = x.
$$

Comparing with the multiple choice options, the correct choice is option 3:
$$
\log_2 128 = x.
$$
