Understand that rewriting a number in standard form involves expressing it as a decimal number between 1 and 10 multiplied by a power of ten.
Identify the given number: 3.41 × 10-4. This is already in scientific notation, where 3.41 is the coefficient and 10-4 is the power of ten.
To convert this into standard decimal form, move the decimal point in the coefficient 3.41 four places to the left, because the exponent is -4.
Moving the decimal point four places to the left from 3.41 results in 0.000341.
Verify the conversion by checking that the number of decimal places moved matches the exponent of ten, ensuring the correct standard form is achieved.
