The notation "4.74E-6" is already in scientific notation. It represents the number \( 4.74 \times 10^{-6} \).
In scientific notation, the format is generally written as \( a \times 10^n \), where \( a \) is a number greater than or equal to 1 and less than 10, and \( n \) is an integer. In this case, \( 4.74 \) is in the correct range, and the exponent \( -6 \) indicates that the decimal point of 4.74 should be moved 6 places to the left, which gives a very small number.
So, \( 4.74E-6 \) is equivalent to \( 4.74 \times 10^{-6} \).
