### Question 19/26

A scientist used the function \( f(m) = 3 \left(2\right)^{2m+1} \) to conduct her experiment. Consider the following expressions:

I. \( 6 \left(2\right)^{2m} \)  
II. \( 6 \left(4\right)^m \)  
III. \( 6 \left(6\right)^{2m} \)

**The function \( f(m) \) is equivalent to:**

- **A. I and II**
- **B. I, only**
- **C. II, only**
- **D. I and III**

**Explanation:**

We need to analyze if the given expressions (I, II, and III) are equivalent to the function \( f(m) = 3 \left(2\right)^{2m+1} \).

1. **Expression I: \( 6 \left(2\right)^{2m} \)**

   Rewrite \( f(m) \):
   \[
   f(m) = 3 \cdot 2^{2m} \cdot 2^1 = 3 \cdot 2 \cdot 2^{2m} = 6 \cdot 2^{2m}
   \]
   Therefore, \( f(m) \) is equivalent to Expression I.

2. **Expression II: \( 6 \left(4\right)^m \)**

   Rewrite \( f(m) \):
   \[
   f(m) = 3 \cdot 2^{2m+1} = 3 \cdot 2 \cdot 2^{2m} = 6 \cdot 2^{2m} \implies 6 \cdot (2^2)^m = 6 \cdot 4^m
   \]
   Therefore, \( f(m) \) is equivalent to Expression II.

3. **Expression III: \( 6 \left(6\right)^{2m} \)**

   Analyze Expression III if:
   \[
   f(m) = 6 \cdot 6^{2m}
   \]
   This does not hold as both the bases are different.

Thus, \( f(m) \) is equivalent to both Expressions I and II.

**Answer: A.
