The expression would be 
after the negative exponents have been removed.
A negative exponent basically tells us to "flip" the side of the fraction it's on. This means that y⁻⁶ on the numerator would go to the denominator, and that x⁻⁴ on the denominator would go to the numerator. This gives us:

Answer:
<em>V = 65.9 cubic millimeters</em>
Step-by-step explanation:
<u>The Volume of a Right Circular Cone</u>
Given a right circular cone of radius r and height h, its volume is calculated as follows:
The cone shown in the image has a radius of r=3 mm and a height of h=7 mm, thus the volume is:
Taking pi as 3.14:
Calculating:
V = 65.9 cubic millimeters
Solution: We are given:
The first week, Bean sprout grows 3 inches
The second week, Bean sprout grows 2 inches
The third week, Bean sprout grows 1.333... inches
Bean sprout follows a particular each week. Every week it grew 2/3 (0.667) less than the week before.
For the first week it was 3 inches, for the second week it was inches, for the third week it was
and therefore, for the fourth week it will be
Therefore, bean sprout have grown 0.8889 inches in its fourth week.
