Question

Compute the following and give your answer in scientific notation:
(3.51 x 10-²) - 2.94 × 10-²
=
× 10^

Answer 1

Answer is 5.7 x 10^-3

Explanation:

Move the decimal 3 times to right in the number so that the resulting number, m = 5.7, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -3
Write in the scientific notation form, m × 10n
= 5.7 × 10-3
