Question

Can someone please do it for me i did a few but i need the rest

Answer 1

Don’t worry! I am happy to help you! Standard form is just the number alone. In this case, here are the numbers written out for you.

1. 53
2. 9,400
3. 707,000
4. 0.0026
5. 0.08651
6. 0.0000067

The next part here is scientific notation. The first number has to be greater than 1, but less than ten, and the number you multiply by is powers of 10, sometime positively and sometimes negatively. You can search up the powers of 10 chart to find more. Here they are written in scientific notation.

7. 5.61 * 10^3
8. 1.4 * 10^1
9. 5.64 * 10^7
10. 7.52 * 10^-1
11. 6.4 * 10^-3
12. 5.81 * 10^-4

For this next part, you have to get these answers and express it in scientific notation. Here are these answers with the work.

13. 69,000,000 + 212,000 = 69,212,000.
Scientific notation: 6.9212 * 10^7

14. 43,000 + 521,000 = 564,000
Scientific notation: 5.64 * 10^5
