Answer: 2) 1.45 × 10⁻⁵
3) 3.99 × 10⁴
<u>Step-by-step explanation:</u>
(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
+<u> 7.4 x 10³ </u> ⇒ <u> 0.74 x 10⁴</u>
3.99 x 10⁴
The area of a rectangle is the multiplication of the sides.
So 34.5 * 36.5 = 1259.25 squared inches.
