Question

perform each of the following operations using scientific nation.

(2.3 × 10³)(4.0 × 10^5)

Answer 1

(2.3 x 10^3)(4.0 x 10^5) =
2300 * 400000 = 920,000,000 or 9.2 x 10^8

or
(2.3 * 4.0)(10^3 * 10^5) =
9.2 * 10^8 = 920,000,000

Answer 2

Hey there, Lets solve this equation together. 

$(2.3 x 10^3)(4.0 x 10^5) = 2300 * 400000 = 920,000,000 or 9.2 x 10^8 Also can be written as (2.3 * 4.0)(10^3 * 10^5) = 9.2 * 10^8 = 920,000,000$
