Question

Write an expression in simplest form for the area of a square with a side of 8x^3 units.

Answer 1

The value of the side of a square is 8x^3 units.
All sides in a square are the same.

For a general rectangle, the area is: Area = base x height.
The square: base=height; so: Area = side x side = side ^2

With this information, we simply plug in that side-length:
Area = (8x^3)^2
Simplify as necessary. :)
