Final answer:

After multiplying the coefficients and adding the exponents, the expression 6a^6b × 2ab simplifies to 12a^7b^2. None of the provided options match this simplified expression correctly. Therefore, the correct answer, 12a^7b^2, is not listed among the options.

The correct answer is D.

Step-by-step explanation:

To simplify the expression 6a^6b × 2ab completely, we need to apply the rules of exponents and multiplication. We'll multiply the coefficients (6 and 2) and add the exponents of like bases.

First, multiply the coefficients:

6 × 2 = 12

Next, apply the rule of exponents, which states that when multiplying like bases, you add the exponents:

a^6 × a = a^(6+1) = a^7

Finally, do the same with the b variables:

b × b = b^(1+1) = b^2

Putting it all together, we get:

12 × a^7 × b^2, which is choice D) 12a^7b^2.

However, none of the provided answer options correctly matches the simplified expression. The correct answer is 12a^7b^2, but this is not listed among the options A) 8a^6b, B) 12a^6b, C) 8a^6.
