Write 3.2x10^7 in expanded form:

32,000,000
3,200,000,000
32,000,000,000
320,000,000

The correct answer is: 32,000,000

The correct choice for writing 3.2x10^7 in expanded form is 32,000,000. To understand this, consider that the notation 3.2x10^7 means that you take the number 3.2 and move the decimal point 7 places to the right. Each place moved to the right corresponds to multiplying by 10, so effectively, you are increasing the value significantly. Starting with 3.2, when you move the decimal point 7 places to the right, you add zeros to fill the gaps, resulting in 32,000,000 (which is 3.2 followed by 7 zeros). This method confirms that 3.2x10^7 accurately translates to 32,000,000, which represents a large quantity in standard form.
