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 equation

$$
2^x = 128.
$$

Recall the definition of logarithms: if

$$
a^b = c,
$$

then this is equivalent to

$$
\log_a(c) = b.
$$

In our case, we have $a = 2$, $b = x$, and $c = 128$. Applying the definition yields

$$
\log_2(128) = x.
$$

Thus, the exponential equation rewritten in logarithmic form is

$$
\log_2(128) = x.
$$

We can also verify this by recognizing that $128 = 2^7$, so

$$
\log_2(128) = \log_2(2^7) = 7,
$$

which tells us that $x = 7$.

Among the given choices, the correct logarithmic equation is the one that matches

$$
\log_2(128) = x.
$$
