write in scienctific notation:
0.003191
To write a number in scientific notation, you need to express it as a product of a number between 1 and 10 and a power of 10. Here's how to write 0.003191 in scientific notation:
First, we count the number of decimal places we need to move to the right to have a non-zero digit before the decimal point. In this case, we need to move four decimal places to the right, giving us 3191.
Next, we express 3191 as a number between 1 and 10 by moving the decimal point one place to the left. This gives us 3.191.
Finally, we multiply 3.191 by 10 raised to the power of -4 (since we moved the decimal point four places to the right). Therefore, 0.003191 in scientific notation is written as 3.191 x 10^-4.
