1.304 x 10⁰ = 1.304 x 1 = 1.304
1.304 x 10¹ = 1.304 x 10 = 13.04
1.304 x 10² = 1.304 x 100 = 130.4
1.304 x 10³ = 1.304 x 1,000 = 1,304
1.304 x 10⁴ = 1.304 x 10,000 = 13,040
1.304 x 10⁵ = 1.304 x 100,000 = 130,400
1.304 x 10⁶ = 1.304 x 1,000,000 = 1,304,000
1.304 x 10⁷ = 1.304 x 10,000,000 = 13,040,000
1.304 x 10⁸ = 1.304 x 100,000,000 = 130,400,000
* 1.304 x 10⁹ = 1.304 x 1,000,000,000 = 1,304,000,000 *
----------------
ANSWER:
1.304 x 10⁹ = 1.304 x 1 Billion
