Expanded Notation of 2,784 = (2 x 103) + (7 x 102) + (8 x 101) + (4 x 100).
1.5 x 108
2.5 x 105 = 250,000
In expanded index notation, 1344 can be expressed as (1.344 \times 10^3). This means that the number 1344 is equivalent to 1.344 multiplied by 10 raised to the power of 3. Expanded index notation is a way to represent numbers in scientific notation, making it easier to work with very large or very small numbers.
To write 267853 in expanded notation using powers of ten, you would break down the number based on its place value. The number 267853 can be expressed as 2 x 10^5 + 6 x 10^4 + 7 x 10^3 + 8 x 10^2 + 5 x 10^1 + 3 x 10^0. This expanded notation representation shows the value of each digit based on its position in the number, multiplied by the corresponding power of ten.
9.11*103 IS in standard notation.
I am stuck on that one too sorry.
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
A power
2¹ = 2
The mantissa is located before the multiplication symbol and the power of 10 in scientific notation.
You mean, scientific notation of 186000? 1.86*105
a square times n to the 3rd power
1.5 x 108
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.
