0.0049 in scientific notation

The steps below can be used to represent the number 0.0049 in scientific notation:

1 - The resulting number, m (= 4.9), must be higher than or equal to 1 and less than 10, thus moving the decimal three times to the right so there is one non-zero digit to the left of the decimal point.

The exponent will be a negative number n (= -3), as we have moved the decimal 3 times to the right.

2 - Write the number in scientific notation form: m × 10n, where m = 4.9 and n = -3.

Hence, the number 0.0049 written in scientific notation is 4.9 × 10^-3
