To identify which expression correctly uses the Product Rule of Exponents, we first recall the Product Rule of Exponents, which states:

am×an=am+n

Given that the simplified expression is 2412, let's look at the options provided:

  1. 124⋅128
    This can be written as:
    124×128=124+8=1212 (not 2412)

  2. 64⋅43
    This can be written as:
    64×43 (this does not apply the product rule or result in 2412)

  3. 244⋅248
    This can be written as:
    244×248=244+8=2412 (not 2412, also does not apply the correct variables)

  4. 243⋅244
    This can be written as:
    243×244=243+4=247 (not 2412)

None of the options correctly apply the Product Rule of Exponents to produce 2412. However, based on the request for a correct application of the Product Rule:

Correct Answer: 244⋅248
This one uses the Product Rule correctly but simplifies to 2412, which is different from 2412 indicated. It appears like a mismatched understanding of the final answer needed.

Explanation: If indeed 2412 was a misunderstood or a wrong simplest parameter, the closest correct application under exponential laws suggests option three was the only one using the right rule, albeit not reaching the "final co-efficient number" of 2412 legally. But if further clarification is needed on what 2412 refers to, please provide!
