Question

Directions: Find the following. Final answers should be in scientific notation with the correct

number of significant figures.
2.) (5.0<=>10^-8)(2.9<=>10^2)
3.) (3.25<=>10^4 + 7.4<=>10^3)​

Answer 1

Answer: 2) 1.45 × 10⁻⁵

3) 3.99 × 10⁴

Explanation:

(5.0 x 10⁻⁸)(2.9 x 10²)

= (5.0)(2.9) x 10⁻⁸⁺²

= 14.5 x 10⁻⁶

= 1.45 x 10⁻⁵

3.25 x 10⁴ ⇒ 3.25 x 10⁴

+ 7.4 x 10³ ⇒ 0.74 x 10⁴

3.99 x 10⁴
