Calculate 6.25×10^6 − 4.73×10^6 . Express your answer in scientific notation to 2 decimal places. (1 point)
The calculation is as follows:
6.25×10^6 − 4.73×10^6
= (6.25 - 4.73) × 10^6
= 1.52 × 10^6
Therefore, the answer in scientific notation to 2 decimal places is 1.52 × 10^6.
4.3514 X 10^9 - 2.25 X 10^8 In scientific notation, do not round answer
The calculation is as follows:
4.3514×10^9 - 2.25×10^8
To subtract the two numbers in scientific notation, we first need to make sure that the exponents are the same. In this case, we multiply 2.25×10^8 by 10 to get 2.25×10^9.
4.3514×10^9 - 2.25×10^9
= (4.3514 - 2.25) × 10^9
= 2.1014 × 10^9
Therefore, the answer in scientific notation is 2.1014 × 10^9.
