Question

Choose the correct expressions using the fewest number of bases possible that are equivalent to the current expression.

Let a and b be positive integers. 23a × 23b =?

1. 23a+b
2. 23a−b
3. 23ab
4. 23b−a

Answer 1

The correct expression that is equivalent to 23a × 23b is 23a+b.

Step-by-step explanation:

The correct expression that is equivalent to 23a × 23b is 23a+b. When multiplying two expressions with the same base, you add the exponents.

In this case, the exponents are a and b, so you add them together to get a+b. Therefore, the correct expression is 23a+b.
