10 pow n + (3.4 pow n+2) divided by 9 what is least positive integral value of k

We are tasked with finding the least positive integral value of \( k \) such that the following expression holds:

\[
10^n + \frac{3.4^{n+2}}{9}
\]

Let's break it down step by step.

### Step 1: Expression Breakdown

The given expression is:

\[
10^n + \frac{3.4^{n+2}}{9}
\]

Here, \( 10^n \) is straightforward as it refers to \( 10 \) raised to the power \( n \). The second part involves \( 3.4^{n+2} \), which is divided by 9. We need to simplify this and find a suitable \( k \).

### Step 2: Interpretation of 3.4

If the base 3.4 is meant to be treated directly (as a decimal), the expression remains as:

\[
10^n + \frac{(3.4)^{n+2}}{9}
\]

Alternatively, if there's a typo and you meant \( 3^n \) or another simpler form, please clarify. 

### Step 3: Finding \( k \)

Now, let's focus on finding the least value of \( n \) such that the overall expression simplifies to an integer.

- For each \( n \), compute \( 10^n \).
- Compute \( (3.4)^{n+2} \).
- Then divide by 9.
  
Would you like me to compute these for small values of \( n \)? Let me know if you need more detailed clarification.

Do you have any questions so far?  
Here are 5 related questions to explore further:

1. What if the base is meant to be an integer instead of 3.4?
2. How does the value of \( k \) change for other bases?
3. What happens when \( n \) is negative or non-integer?
4. Can you explore the behavior of the function graphically?
5. What role does the divisor (9) play in simplifying the expression?

**Tip:** When dealing with complex expressions, double-check assumptions about notation to ensure proper interpretation!
