Final answer:
To express 10 • 10 using an exponent, we use 10², which equals 100. Thus, the Sun is 100 × 10 million miles away from Earth, which is equivalent to approximately 150 million kilometers.
Step-by-step explanation:
The expression 10 • 10 written using an exponent is 10², which signifies 10 to the power of 2 or 10 squared. This means that you multiply 10 by itself one time, which results in 100. Therefore, the Sun is approximately 10² × 10 million miles away from Earth, which equates to 100 × 10 million miles. Based on the scientific notation provided in the reference materials, the distance from Earth to the Sun is 1.496 × 10¹¹ meters, which is roughly equivalent to 150 million kilometers when converted from meters.
