Answer 1

1) 47*23=50*20=1000
47*23=1081
2) 518*19=500*20=10 000
518*19=9 842
3) 192*485=200*500=10 0000
192*485=93 120
4) 285*209=300*200=60 000
285*209=59 565

Answer 2

Calculation of the Exact Product

To calculate the exact product of the given multiplication, we need to round the multipliers to the nearest whole number and then find the exact value of the product. Let's perform the calculation step by step:

1. Rounding the multipliers: - 47 * 23 = 1081 - 518 * 19 = 9842 - 192 * 485 = 93120 - 285 * 209 = 59565

2. Finding the exact value of the product: - 1081 + 9842 + 93120 + 59565 = 163608

Therefore, the exact value of the product is 163608.

Difference from the Approximate Value

To find the difference between the exact value of the product and the approximate value, we need to calculate the approximate value first. Let's calculate the approximate value of the given multiplication:

- 47 * 23 ≈ 1081 - 518 * 19 ≈ 9842 - 192 * 485 ≈ 93120 - 285 * 209 ≈ 59565

Now, let's calculate the approximate value of the product:

- 1081 + 9842 + 93120 + 59565 ≈ 163608

The approximate value of the product is also 163608.

Therefore, the exact value of the product is the same as the approximate value, and there is no difference between them.
