In scientific notation, the measurement of each figure to three significant measurements are as follows:

• 87.073 meters = 8.71 × 10⁻¹ meters
• 4.3621 × 10⁸ meters = 4.36 × 10⁸ meters
• 0.01552 meter = 1.55 × 10² meters
• 9009 meters  = 9.01 × 10² meters
• 1.7777 x 10-3 m = 1.78 × 10⁻³ meters
• 629.55 meters = 6.30 × 10² meters

A significant figure is the digits in a number that is dependable and absolutely essential to express the quantity of a figure in positional notation. They are utilized to represent the appropriate degree of precision.

A scientific notation is used to express a large number in an easy decimal way multiplied by its power of 10.

From the given information, in scientific notation, and to three significant figures, we have:

• 87.073 meters = 8.71 × 10⁻¹ meters
• 4.3621 × 10⁸ meters = 4.36 × 10⁸ meters
• 0.01552 meter = 1.55 × 10² meters
• 9009 meters  = 9.01 × 10² meters
• 1.7777 x 10-3 m = 1.78 × 10⁻³ meters
• 629.55 meters = 6.30 × 10² meters

Therefore, from the above concept, we can conclude that the scientific notation of each figure in three significant figures is shown in bold format.
