Both expressions are the same because they have the same base, which is 3. When you multiply two powers with the same base, you just add their exponents. So in both cases, the exponents of 3 are added together correctly, and the answer is 3 raised to the power of 7. make this shorter

Answer 1

Both expressions are the same because when you multiply two powers with the same base, you add their exponents. So both expressions simplify to 3 raised to the power of 7.
