Answer:

Step-by-step explanation:
Given equation of ellipsoids,

The vector normal to the given equation of ellipsoid will be given by





Hence, the unit normal vector can be given by,



Hence, the unit vector normal to each point of the given ellipsoid surface is

The smallest value for n is -3
When you move the decimal point to the right, the exponent on the 10 will be negative
move the decimal point to the right 3 times and you get 2.22 x 10^-3
2.22 is greater than two
Answer: 5.60
Step-by-step explanation: Divide 2.10 by 3. You get 0.7. Then multiply 0.7 by 8 and you get 5.60.
