To convert 4.6 × 10−4 into standard form, you need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. The number is multiplied by 10 raised to the power of the exponent.
In this case, the exponent is -4, which means you need to move the decimal point four places to the right.
Moving the decimal point four places to the right gives you the standard form of 0.000046. So, the correct answer is 0.000046.
