Answer:
Option B
Explanation:
We want to multiply:
3^6 by 3^4.
When we multiply two terms with the same base and different exponent, we keep the base and add the exponents. So
3^(6)*3^(4) = 3^(6+4) = 3^10, which is option A.
Equivalent expressions are those in which the base is 3, and the sum of the exponents is 10. So C and D are also equivalent expressions.
The lone which is not is B, which is the answer to this question.
