Expanded Notation written using the powers of 10
This is an extension of writing the equation in expanded notation!
Therefore I will use the information from that to explain;
First I'll do out a table showing powers
So hopefully you see the pattern in the above table!
0.012 in expanded form = 0.01 + 0.002
10x10x10x10
-16807
Standard form: 1.5*10-1 seconds, expanded form: (0.1 + 0.05) seconds.
43 = 64
124 = 20,736
To write 50,098 in expanded form, you can break it down as follows: 50,098 = 50,000 + 98 The 50,000 can be converted to 50 * 10^3 (10 to the power of three), and the remaining 98 can be written as 98. Therefore, the expanded form of 50,098 would be 50 * 10^3 + 98.
5*5 or 10
To write 305.5 in expanded form, you break it down into its place values. It can be expressed as 300 + 0 + 5 + 0.5, which represents 300 (the hundreds), 0 (the tens), 5 (the ones), and 0.5 (the tenths). Thus, the expanded form is 300 + 5 + 0.5.
5(100) + 4(10) + 6
2.5 x 105 = 250,000
The first step to writing in expanded form is dividing by a power of ten such that the answer has units as its greatest place value. In this case, this can be done by dividing by 1,000. 6831.043/1000 = 6.831043. The next step is to write the power of ten we used alongside as a multiplication. 1,000 is the 4th power of ten, which can be written as 104. Therefore, 6831.043 in expanded form is 6.831043x104
