Word Form:

Step1: Identify place values

The number 1,784,000 has digits in the millions, hundred - thousands, ten - thousands, thousands, and the rest are zeros. The digit 1 is in the millions place, 7 in the hundred - thousands, 8 in the ten - thousands, 4 in the thousands, and the last three digits are 0 (hundreds, tens, ones).

Step2: Write in words

We break down the number: 1 million, 7 hundred - eighty - four thousand. Since the last three digits are zero, we don't need to mention the hundreds, tens, or ones place. So in word form, it is "one million seven hundred eighty - four thousand".

Step1: Identify place values and their multipliers

The place values for a number are based on powers of 10. The digit 1 is in the millions place, which is $10^6$ (1,000,000), 7 is in the hundred - thousands place ($10^5$ or 100,000), 8 is in the ten - thousands place ($10^4$ or 10,000), 4 is in the thousands place ($10^3$ or 1,000), and the digits in the hundreds ($10^2$), tens ($10^1$), and ones ($10^0$) places are 0.

Step2: Write the expanded form

We multiply each digit by its corresponding place value and add them together. So, $1\times1000000 + 7\times100000+8\times10000 + 4\times1000+0\times100 + 0\times10+0\times1$. Simplifying this, we get $1000000+700000 + 80000+4000+0 + 0+0$.
