1. 2.0 x 10^-2
2. 2.2 x10^6
3. 2.0 x 10^4
Just covert each until you reach the end, like you know that there are 356 days in a year and 100 years in a century.
PS They're in scientific notation
4.6, 6.41, 6.46
Hope this helps her!

Answer:
11
Step-by-step explanation:
- 9+3(8-3(7-5))-4
- 9+3(8-3(2))-4
- 9+3(8-6)-4
- 9+3(2)-4
- 9+6-4
- 15-4
- 11
I first delt with simplifying the parentheses till step five. Then in five I just added 9+6 because it came before the -4. But PEMDAS is very important when doing these problems because it tell you the order
- P (parentheses)
- E (exponents)
- M (multiply)
- D (divide)
- A (add)
- S (subtract)
- **the biggest thing is that with multipe and divide it depends what comes first. If you see divide before multipe in the problem just do it that way. It is the same way with add and subtract but The multiple/divide group ALWAYS comes BEFORE add/subtract
You can just look the answer up on safari or google don’t bother putting it on here because it takes 5 months to get a reply and when you do it’s me saying you should look it up but you don’t feel like it so your grade suffers
