Answer:
3159.853 km
Step-by-step explanation:
The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:
9984670 = (x)(x) which rearranges to 998470 = x^2
get the square root and you get:
x = 3159.853 km

Answer: 
Step-by-step explanation:
The surface area of a rectangular prism can be calculated with the following formula:

Where "l" is the length of the rectangular prism, "w" is the width and "h" is the height.
In this case you can say that the length, the width and the heigth of this rectangular prism, are the following:

Knowing these values, you can substitute them into the formula shown before:

Finally, you must evaluate in order to calculate the surface area of the rectangular prism.
You get that this is:

Answer:
Step-by-step explanation:
Terms with the exponents are like terms, we can subtract the exponents from each other when we divide.
(8y^7)/(4y^5) = 2y^(7-5) = 2y^2
