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.

Step 1: Count the number of decimal places needed to move the decimal point from its original position to the position just after the first significant digit. In this case, the original position of the decimal point is after the last digit, so we need to move it 4 places to the right to get it after the first significant digit.

Step 2: Write 0.000456 as 4.56 and multiply it by 10 raised to the power of -4 (the number of decimal places we moved the decimal point in step 1).

So, 0.000456 in scientific notation is written as 4.56 x 10^-4.

To write 0.000456 in scientific notation, we can express it as a number between 1 and 10 multiplied by a power of 10. The number 0.000456 can be written as 4.56 x 10^(-4).
