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 order to write a number in scientific form, you first need to divide it by a power of 10 such that the greatest place value is the units. In this case, you can divide by 0.00001 to get 7.52. The next step is to represent this power of 10 next to the number as a multiplication. In this case we used 0.00001, which is 10-5 Thus 0.0000752 in scientific notation is 7.52x10-5
9.11*103 IS in standard notation.
3.77x 10 to the fourth power in standard notation = 37,700
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
The mantissa is located before the multiplication symbol and the power of 10 in scientific notation.
2¹ = 2
You mean, scientific notation of 186000? 1.86*105
Powers are a convenient shortcut for repeated multiplication.
1.5 x 108
a square times n to the 3rd power
2.5 x 105 = 250,000
1.72 x 104 is 17200 when expanded as 1.72 x 104 is already in standard notation.
