a multiplication form is repeated addition
The first step in representing a number in expanded form is to divide it by a power of 10 until the greatest place value is the units. In this case we can divide by 100,000 to get 7.16948 Next you need to indicate the power of ten that was used. We used 100,000 which is the fifth power of ten, or 105. This needs to be added after the above answer as a multiplication. Thus, 716948 in expanded form is 7.16948x105

Write 2,784 in expanded notation as the sum of multiplication expressions
(1 x 1000000000000) + (4 x 100000000000) + (3 x 10000000000) + (5 x 1000000000) + (6 x 100000000) + (0 x 10000000) + (0 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
5.27 = (5 x 1) + (2/10) + (7/100)
5.27 = (5 x 1) + (2/10) + (7/100)
(9x10)+(5x1)+(4/10)+(1/100)+(7/1000)
9*10 + 5*1 + 4*0.1 + 1*0.01 + 7*0.001
3.842 = (3 x 1) . (8/10) + (4/100) + (2/1000)
6.837 = (6 x 1) + (8/10) + (3/100) + (7/1000)
To write a number is expanded form, you first need to divide it by a power of 10 such that the result has a greatest value of units. In this case, we can divide by 10,000,000 to get 8.9415873 We divided by 10,000,000 which is the 7th multiple of 10, or 107, so we need to add this to the decimal value as a multiplication. Thus, the answer to 89415873 in expanded form is 8.9415873x107
