2 x 2 x 2 x 2 = 16
32,400
It is written as 8.35*104
8.29*104 = 82,900

exponential form
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
6.3*104 = 63,000
Any number to the first power is that number - so 3 to the first = 3 Any number to the second power is that number multilpied by itself, so 3 to the second = 3 x 3 Any number to the third power is itself to the second power multiplied by itself, so 3 to the third = 3 x 3 x 3 and so on.. so three to the fourth = 3 x 3 x 3 x 3 As three is a prime number there are no other factors.
