Find the simplified form of the expression. Give your answer in scientific notation.

(3 × 106)(8 × 10–4)

The simplified form of the expression is:

(3 × 10^6)(8 × 10^(-4))

To simplify, we can multiply the coefficients and add the exponents of 10:

(3 × 8) × (10^(6 + (-4)))

24 × 10^2

= 2.4 × 10^3

Therefore, the simplified form of the expression is 2.4 × 10^3.
