log 3 squared = (x minus 4)
log 2 cubed = (x minus 4)
log Subscript 2 Baseline (x minus 4) = 3
log Subscript 3 Baseline (x minus 4) = 2

(look at the picture below)

Final answer:

The logarithmic equation that has the same solution as x - 4 = 2^3 is log2(x - 4) = 3.

Step-by-step explanation:

The logarithmic equation that has the same solution as x - 4 = 23 is log2(x - 4) = 3.

To explain this, we need to understand how logarithms and exponentiation are related. When an equation is written in exponential form, such as 23 = 8, we can rewrite it in logarithmic form as log2(8) = 3. In this case, we have x - 4 = 23, which means that 23 = (x - 4). Using the logarithmic property, we can rewrite this equation as log2(x - 4) = 3.

Given:

The given equation is
x-4=2^(3)

Solving the equation
x-4=2^(3), we get;


x-4=8


x=12

We need to determine the logarithmic equation that is equivalent to the given equation.

Option A:
\log 3^(2)=(x-4)

Simplifying, we get;


\log 9=x-4


\log 9+4=x


4.95=x

Since, the values of x are not equivalent, the equation
\log 3^(2)=(x-4) is not equivalent to
x-4=2^(3)

Option A is not the correct answer.

Option B:
\log 2^(3)=x-4

Simplifying, we get;


\log 8=x-4


\log 8+4=x


4.9=x

Since, the values of x are not equivalent, the equation
\log 2^(3)=x-4 is not equivalent to
x-4=2^(3)

Option B is not the correct answer.

Option C:
\log _(2)(x-4)=3

Simplifying, we get;


x-4=2^(3)


x-4=8


x=12

Since, the values of x are equivalent, the equation
\log _(2)(x-4)=3 is equivalent to
x-4=2^(3)

Hence, Option C is the correct answer.

Option D:
\log _(3)(x-4)=2

Simplifying, we get;


x-4=3^2


x-4=9


x=13

Since, the values of x are not equivalent, the equation
\log _(3)(x-4)=2 is not equivalent to
x-4=2^(3)

Hence, Option D is not the correct answer.
