Answer:
The answer is -3.023 times 10^8. The calculation is 5.77 times 10^7 minus 3.8 times 10^8, which is equal to -3.023 times 10^8.
Explanation:
1. Rewrite the two numbers in scientific notation:
5.77 x 10^7 and 3.8 x 10^8
2. Subtract the exponents to determine the exponent of the answer:
10^7 - 10^8 = 10^7
3. Subtract the coefficients to determine the coefficient of the answer:
5.77 - 3.8 = 1.97
4. Put the result in scientific notation:
1.97 x 10^7
Answer: 1.97 x 10^7
