Final answer:
To compute the expression and write the result in scientific notation, multiply the coefficients and apply the rule of exponents. The final answer will be in the form of a × 10^b, where 'a' is the result after multiplication and 'b' is the sum of the exponents.
Step-by-step explanation:
To perform the computation and write the result in scientific notation, we can use the product rule of exponents. Multiply the coefficients and then add the exponents.
(6.9 × 10³) (3.2 × 10-³) = 6.9 × 3.2 × 10(3 - 3) = 22.08 × 100 = 22.08
Since the exponent of 10 is 0, we can express the result as 22.08 × 100 = 2.208 × 101 in scientific notation.
