Expanded Notation of 2,784 = (2 x 103) + (7 x 102) + (8 x 101) + (4 x 100).
2.756 x 103
To express a number in expanded notation, you first need to divide it by a power of 10 such that the units is the greatest place value. In this case, you would divide by 100 to get 8.523. The next step is to add that power of ten to the sum as a multiplication. We use 100, which is the second power of 10. This can be written as 102. Thus 852.3 can be written in expanded notation as 8.523x102
2¹ = 2
You mean, scientific notation of 186000? 1.86*105
The mantissa is located before the multiplication symbol and the power of 10 in scientific notation.
1.5 x 108
a square times n to the 3rd power
Powers are a convenient shortcut for repeated multiplication.
2.5 x 105 = 250,000
1.72 x 104 is 17200 when expanded as 1.72 x 104 is already in standard notation.
This is a number written in scientific notation, which expanded would equal 4,538,000,000.
Expanded Notation of 2,345 = (2 x 1000) + (3 x 100) + (4 x 10) + (5 x 1)
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 10^2 = 100 10 to the power of 2 is One Hundred (2 zero's-after the 1) So hopefully you see the pattern in the above table!
Superscript or e notation. 5 to the 3rd power is written as 5 with superscript 3. e notation is for multiplication by powers of 10. So 4 times 10 to the 6'th power (4 million) is 4e6 in e notation.
Expanded Notation of 642,275 = (6 x 100,000) + (4 x 10,000) + (2 x 1,000) + (2 x 100) + (7 x 10) + (5 x 1)
power then multiplication
? An expression which is obtained by performing a finite number of the following operations on symbols representing numbers: addition, subtraction, multiplication, division, raising to a power.
7.50 x 106 or 7.50 times 10 to the 6th power.
3 x 10^3 +1 x 10^1 +8
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
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
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
4768 = 4*10**3 + 7*10**2 + 6*10**1 + 8*10**0 Notes: * denotes multiplication ** denotes exponentiation Result of anything raised to the power of zero as in 10**0 is equal to 1
