A. 1
B. 2
C. 3
D. 4


Sagot :

Certainly, let's solve the equation step-by-step.

The given equation is:

[tex]\[ \frac{1}{36} = 6^{x-4} \][/tex]

Step 1: Rewrite [tex]\(\frac{1}{36}\)[/tex] using base 6.

We know that:

[tex]\[ \frac{1}{36} = \frac{1}{6^2} = 6^{-2} \][/tex]

So, the equation becomes:

[tex]\[ 6^{-2} = 6^{x-4} \][/tex]

Step 2: Equate the exponents.

Since the bases on both sides of the equation are the same (both are base 6), we can set the exponents equal to each other:

[tex]\[ -2 = x - 4 \][/tex]

Step 3: Solve for [tex]\(x\)[/tex].

To isolate [tex]\(x\)[/tex], we add 4 to both sides of the equation:

[tex]\[ -2 + 4 = x - 4 + 4 \][/tex]

[tex]\[ 2 = x \][/tex]

So, the value of [tex]\(x\)[/tex] is:

[tex]\[ \boxed{2} \][/tex]
