Final answer:
To simplify 2 × 2³, calculate 2³ first, then multiply by 2 to get 16. 25 × 2 equals 50. In index form, 2 × 2³ is 2^4 and 25 × 2 is 25^1 × 2^1
Step-by-step explanation:
To simplify 2 × 2³, we first calculate 2³ which equals 2 × 2 × 2 = 8. Then, we multiply 2 by 8 to find the final result, which is 16. Therefore, 2 × 2³ = 16.
For the expression 25 × 2, we simply multiply 25 by 2 to get 50. So, 25 × 2 = 50.
In index form, 2 × 2³ can be written as 2 × 2³ = 2^4. And 25 × 2 can be expressed as 25 × 2 = 25^1 × 2^1
