What is the scientific notation for 0.0000037?
you move the decimal point from where it is to after the 3
so in the end, you count up how many numbers you counted to get to the 3
the scientific notation becomes:
3.7 X 10to the 6th power
How do you do scientific notation on a calculator?
The answer depends on your calculator but many have shortcut keys for "x10x" or something similar.
How are quantities expressed in scientific notations?
Very large numbers or very small numbers can be expressed in scientific notation as in the following examples:
1,000,000,000,000 = 1.0*1012
0.0000001 = 1.0*10-7
What is 0.0540 in scientific notation?
Scientific notation is in the form of a x 10^n, where 0 First, move the decimal point to make the number less than 10 but greater than 0. .0540→5.4. Next, count how many decimal places you moved the decimal and in what direction. .0540→.540(1 place right)→5.4(2 places right). You moved it two places to the right. Since you made the number larger, you must make the exponent smaller to compensate. And since you moved it 2 places, you will make the exponent -2. (n must be negative since you positively increased a). So: .0540 = 5.4 x 10^-2
How do you write 400 in scientific notation?
Note that 400 is same as 400.0. Then, shift 2 decimal places to the left from the starting point. Therefore, the number in scientific notation is:
4.0 x 102
It is: 4.0*10^2
What rules do we use to convert standard to scientific notation?
Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!
How do you write one and twenty one millionths in standard form?
One and twenty one millionths (1.000021) in standard form is: 1.000021 × 100
What expression represents 5.784 x 10 to the 5th power?
The scientfic notation of 5.784*10^5 represents 578,400
