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
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
To write a number in expanded form, you first need to divide it by a power of ten such that the greatest place value is units. In this case we can divide by 100 to give 8.26. The next step is to write that power of 10 alongside as a multiplication. 100 is the second power of 10 or 102. Thus 826 in expanded form is 8.26x102
