Christian, you can't write those numbers in scientific notation. Are you sure they shouldn't have commas anywhere instead of decimals?
(y+8)2 power divde by x
Christian, I can do them!
7,500 = 7.5 x 10^3
75000000 = 7.5 x 10^7
Sorry - don't know that last one.
To write numbers in scientific notation, follow these steps:
1. Count the number of decimal places you need to move to the left/right to write the number between 1 and 10.
2. Write the decimal part of the number (excluding any trailing zeros) as the base, and multiply it by 10 raised to the power of the number you obtained in step 1.
3. If the original number is negative, include a negative sign in the final answer.
Applying these steps to the given numbers:
1. 1.7500:
- Count the number of decimal places we need to move to the right before reaching a number between 1 and 10: 3.
- As the decimal part of the number is 1.75, we multiply it by 10^3.
- Therefore, 1.7500 in scientific notation is 1.75 x 10^3.
2. 2.75000000:
- Count the number of decimal places we need to move to the right before reaching a number between 1 and 10: 0.
- As the decimal part of the number is 2.75, we multiply it by 10^0, which is 1.
- Therefore, 2.75000000 in scientific notation is 2.75 x 10^0 or simply 2.75.
3. 3.1250:
- Count the number of decimal places we need to move to the right before reaching a number between 1 and 10: 1.
- As the decimal part of the number is 3.125, we multiply it by 10^1.
- Therefore, 3.1250 in scientific notation is 3.125 x 10^1.
