anonymous 4 years ago how do I put this into scientific notation: -1456.90

1. ash2326

-1456.90 -1.45690* 10^3

2. anonymous

-1.45690x 10^3

3. UnkleRhaukus

$-1.4569 \times 10^3$

4. anonymous

but doesn't the coefficient have to be $\le1$ and $\ge10$?

5. ash2326

no, there's no condition like that

6. anonymous

thats what I have in my notes...

7. ash2326

what's written?

8. anonymous

what I said is what is written

9. anonymous

oh, but the signs are supposed to be switched

10. anonymous

its$\ge1$ and $\le 10$

11. ash2326

a* 10^b see the coefficient should be in the range $1 \le a <10$ a minus can come before it if it's a negative number here the coefficient is 1.4569 with a negative sign

12. anonymous

ok thanks

13. ash2326

did you get it??

14. anonymous
