Answer :

Let's solve the equation step-by-step.

We start with the equation:
[tex]\[ 4 \cdot (3)^n = 324 \][/tex]

First, we want to isolate the term with the exponent, [tex]\((3)^n\)[/tex]. To do this, we'll divide both sides of the equation by 4:
[tex]\[ \frac{4 \cdot (3)^n}{4} = \frac{324}{4} \][/tex]

Simplifying both sides, we get:
[tex]\[ (3)^n = 81 \][/tex]

Next, we need to express 81 as a power of the base 3. Observing the numbers, we notice that:
[tex]\[ 81 = 3 \times 3 \times 3 \times 3 = 3^4 \][/tex]

So, we can rewrite the equation as:
[tex]\[ (3)^n = 3^4 \][/tex]

Since the bases are the same, we can equate the exponents:
[tex]\[ n = 4 \][/tex]

Thus, the solution to the equation [tex]\(4 \cdot (3)^n = 324\)[/tex] is:
[tex]\[ n = 4 \][/tex]
