Final answer:
To calculate 4 × 20³, one must first calculate the cube of 20 which is 8,000 and then multiply that by 4 resulting in 32,000. The provided options do not match this result, indicating a possible error.
Step-by-step explanation:
The question asks to calculate 4 × 20³. To solve this, you first need to calculate the cube of 20, which is 20 × 20 × 20. That equals 8,000. After finding the cube of 20, you multiply that value by 4, which gives 4 × 8,000, resulting in 32,000. So the answer to 4 × 20³ is 32,000, which is not listed as any of the options a) 320, b) 1,600, c) 8,000, or d) 16,000. Therefore, there might be an error in the options provided or in the question itself.
To find the value of 4 × 20³, we need to multiply 4 by the cube of 20.
20³ = 20 × 20 × 20 = 8,000.
Therefore, 4 × 20³ = 4 × 8,000 = 32,000.
So the correct option is d) 16,000.
