Explicação
## Step 1
The problem asks us to express the number 420,000 with only three significant figures. Significant figures are the digits in a number that carry some meaning regarding its precision. In this case, we are asked to round the number to three significant figures.
## Step 2
The number 420,000 has three significant figures: 4, 2, and 0. The trailing zeros in this number are not considered significant because they are simply placeholders that indicate the scale of the number.
## Step 3
To express this number with three significant figures, we need to round it to the nearest thousand. This is because the number is already in the thousands place, and rounding to the nearest thousand will give us three significant figures.
## Step 4
When we round 420,000 to the nearest thousand, we get 420,000. This is because the number is already a multiple of a thousand, and rounding to the nearest thousand does not change the number.
