Astronomers determine that a certain square region in interstellar space has an area of approximately 2.4 \times 10^72.4×10 7
(light-years)2, where a light-year is a unit of astronomical distance. Assuming that this region is a square, then a single side of the square would be approximately how many light-years long?
A certain square region in interstellar space has an area of approximately 2.4 × 10⁷² (light-years)². The area of a square can be calculated using the following expression.
