Which number represents 4.6 x 10^-4 in standard form
0.00046
To express 4.6 x 10^-4 in standard form, you need to move the decimal point to the right until only a single digit remains to the left of the decimal point. The number of places you move the decimal point to the right will be determined by the exponent in the scientific notation.
In this case, the exponent is -4, which means you need to move the decimal point four places to the right. Since there is no digit to the left of the decimal point, you can insert zeros as placeholders.
Therefore, 4.6 x 10^-4 in standard form is 0.00046.
To represent 4.6 x 10^-4 in standard form, follow these steps:
Step 1: Move the decimal point to the right or left in order to eliminate the exponent.
In this case, the exponent is negative, so we will move the decimal point to the left.
Step 2: Count the number of places you moved the decimal point.
Since the decimal point was moved 4 places to the left, the exponent is -4.
Step 3: Rewrite the number without the exponent.
Moving the decimal point 4 places to the left gives us 0.00046.
Therefore, 4.6 x 10^-4 in standard form is 0.00046.
