calculate 6.25 x 10^6 - 4.73 x 10^6 express your answer in scientific notation to 2 decimal place
To calculate this, we subtract the values in front of the powers of 10 and keep the same power of 10.
6.25 x 10^6 - 4.73 x 10^6 = 1.52 x 10^6
Therefore, the answer in scientific notation to 2 decimal places is 1.52 x 10^6.
the average distance from earth to mars is 2.25 x 10^8 km. how much farther is neptune from earth to mars? express your answer in scientific notation. do NOT round your answer
To find the distance between Neptune and Mars, we subtract the distance between Earth and Mars from the distance between Earth and Neptune.
The average distance from Earth to Mars is given as 2.25 x 10^8 km.
The average distance from Earth to Neptune is approximately 4.498 x 10^9 km.
To find the distance between Neptune and Mars:
4.498 x 10^9 km - 2.25 x 10^8 km
To subtract these values, we subtract the values in front of the powers of 10 and keep the same power of 10.
4.498 x 10^9 km - 2.25 x 10^8 km = 4.2735 x 10^9 km
Therefore, the distance between Neptune and Mars in scientific notation is 4.2735 x 10^9 km.
give me a different answer but make sure not to round it
To find the distance between Neptune and Mars, we subtract the distance between Earth and Mars from the distance between Earth and Neptune.
The average distance from Earth to Mars is given as 2.25 x 10^8 km.
The average distance from Earth to Neptune is approximately 4.498 x 10^9 km.
To find the distance between Neptune and Mars:
4.498 x 10^9 km - 2.25 x 10^8 km
To subtract these values, we subtract the values in front of the powers of 10 and keep the same power of 10.
4.498 x 10^9 km - 2.25 x 10^8 km = 4.273 x 10^9 km
Therefore, the distance between Neptune and Mars in scientific notation is 4.273 x 10^9 km.
thats wrong
I apologize for the incorrect answer. Let me recalculate the distance between Neptune and Mars without rounding:
Distance from Earth to Mars: 2.25 x 10^8 km
Distance from Earth to Neptune: 4.498 x 10^9 km
To find the distance between Neptune and Mars:
4.498 x 10^9 km - 2.25 x 10^8 km = 4.2735 x 10^9 km
Without rounding, the distance between Neptune and Mars in scientific notation is 4.2735 x 10^9 km.
round it
Apologies for the confusion. Let's round the answer to two decimal places:
Distance from Earth to Mars: 2.25 x 10^8 km
Distance from Earth to Neptune: 4.498 x 10^9 km
To find the distance between Neptune and Mars:
4.498 x 10^9 km - 2.25 x 10^8 km = 4.273 x 10^9 km
Therefore, the distance between Neptune and Mars, rounded to two decimal places, is 4.27 x 10^9 km.
difference in 6.849 x 10^-4 to 3.329 x 10^-2
To find the difference between 6.849 x 10^-4 and 3.329 x 10^-2, we subtract the values in front of the powers of 10 and keep the same power of 10.
6.849 x 10^-4 - 3.329 x 10^-2 = -3.3201 x 10^-2
Therefore, the difference between 6.849 x 10^-4 and 3.329 x 10^-2 is -3.3201 x 10^-2.
0.078 - (5.2 x 10^-3) scientific notation
To find the difference between 0.078 and 5.2 x 10^-3, we subtract the values directly:
0.078 - (5.2 x 10^-3) = 0.078 - 0.0052 = 0.0728
Therefore, the difference is 0.0728. Since the difference does not involve any powers of 10, there is no need to express it in scientific notation.
