The average distance from earth to Mars is 2.25×10 power of 8KM and the distance from earth to Neptune is 4.3514×10 power of 9KM how much further is Neptune from earth than Mars express answer, and scientific notation do not round your answer

Answer 1

To find out how much further Neptune is from Earth than Mars, we can subtract the distance from Earth to Mars from the distance from Earth to Neptune.

1. Distance from Earth to Mars: \( 2.25 \times 10^8 \) km
2. Distance from Earth to Neptune: \( 4.3514 \times 10^9 \) km

Now perform the subtraction:

\[ 4.3514 \times 10^9 \text{ km} - 2.25 \times 10^8 \text{ km} \]

To subtract these two numbers, we need to express them with the same exponent. We can convert \( 2.25 \times 10^8 \) into the form with \( 10^9 \):

\[ 2.25 \times 10^8 = 0.225 \times 10^9 \]

Now we can perform the subtraction:

\[ 4.3514 \times 10^9 - 0.225 \times 10^9 = (4.3514 - 0.225) \times 10^9 = 4.1264 \times 10^9 \text{ km} \]

Thus, Neptune is \( 4.1264 \times 10^9 \) km further from Earth than Mars.
