To write 0.000456 in scientific notation, we need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point.
Count the number of decimal places we moved the decimal point. In this case, it's 4 places.
Therefore, 0.000456 in scientific notation is:
4.56 x 10^-4
To write 0.000456 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.
First, count the number of decimal places in the original number. In this case, there are 4 decimal places.
Next, move the decimal point to the right so that there is only one non-zero digit to the left of the decimal point. In this case, we move the decimal point 4 places to the right.
This gives us 4.56.
Now, express this number as the product of 4.56 and the appropriate power of 10. Since we moved the decimal point 4 places to the right, the power of 10 is -4.
Therefore, 0.000456 in scientific notation is 4.56 x 10^-4.
