Final answer:
2.31 x 10^5 miles is equivalent to 231,000 miles when expressed without using scientific notation. This value can also be converted to kilometers, with 1 mile equaling 1.61 km.
Step-by-step explanation:
The expression 2.31 x 105 miles can be understood as 2.31 multiplied by 100,000 (since 10 to the power of 5 is 100,000). To calculate this without scientific notation, you simply perform the multiplication:
2.31 miles x 100,000 = 231,000 miles.
This is another way to express 2.31 x 105 miles, without using scientific notation. If necessary, this distance can also be converted to other units like kilometers using the conversion factor that 1 mile = 1.61 km.
