The expanded form of 3.4 is 3 + 0.4. In decimal notation, each digit's place value is a power of 10. The 3 is in the tens place, representing 3 * 10, and the 0.4 is in the tenths place, representing 4 * 0.1. Therefore, the expanded form is 3 * 10 + 4 * 0.1.
To write a number in expanded form, you first have to divide that number by a power of 10 that produces an answer where the greatest place value digit is units. In this case, we can divide by 10,000 to get 2.5. The next step is to express the power of 10 we used alongside the number as a multiplication. We divided by 10,000 which is the fourth power of 10 or 104. Thus 25,000 in expanded form is 2.5x104
To write a number in expanded form we first need to divide it by a power of 10 so that the greatest digit is the units (it is currently the tenths) In this case, you can divide by 0.1 to get 4.92 0.1 is the negative oneth power of ten, or 10-1. This needs to be written alongside 4.92 as a multiplication. Thus, the expanded form of 0.492 is 4.92x10-1 * * * * * I believe that the above is the correct answer but for the scientific form. The expanded form is 4*10-1 + 9*10-2 + 2*10-3 or 4/10 + 9/100 + 2/1000
It is in expanded form.
