anonymous 3 years ago Find the simplified form of the expression. Give your answer in scientific notation. (9x10^5) (6x10^-7)

1. anonymous

$5.1*10^{-1}$

2. anonymous

$\left( 9x10^{5} \right)\left( 6x10^{-7} \right)$

3. anonymous

sorry it is 5.4

4. anonymous

can you help me with another

5. anonymous

yes

6. anonymous

What is the simplified form of the expression?|dw:1369551234066:dw|

7. anonymous

is it m

8. anonymous

yes

9. anonymous

$1/4\frac{ c ^{20} }{ m ^{12} }$

10. anonymous

u have to muitiply the external power with the individual no to get it

11. anonymous

o that is not the answer right

12. anonymous

sorry it is the same only with a 4^4 in the numerator

13. anonymous

just remove1/4

14. anonymous

I'm confused

(9x10^5) (6x10^-7) = (9x6) (10^5 x 10^-7) = 54 * 10^(5-7) = 54 * 10^-2 = 54/10^2 = 54/100 = 0.54

16. anonymous

$\frac{ m ^{-12} }{4^{-4} c ^{-20} }$

17. anonymous

so it becomes$\frac{4^{4} c ^{20} }{ m ^{12} }$

18. anonymous

|dw:1369551670166:dw|

19. anonymous

and|dw:1369551862560:dw|

20. anonymous

|dw:1369551868497:dw|

21. anonymous

thats not an option

22. anonymous

then there is a problem in question or the options coz this the solution u will get after solving the question

|dw:1369552089230:dw|

24. anonymous

dah wow ok i was lost

25. anonymous

@Tabbiejack ur option 3 is the same as my answer check it

26. anonymous

its ok

27. anonymous

i see know

28. anonymous

I have another

29. anonymous

ok

A population of 1,750 cheetahs decreases by 11% per year. How many cheetahs will there be in the population after 10 years? Round your answer to the nearest whole number. A. 4969 B. 486 C. 546 D. 1640

31. anonymous

i think its c

32. anonymous

idk

1750 * (1 - 11%)^10 = 1750 (0.89)^10 = 545.68009877440821... = 546

34. anonymous

really i got it right wow

35. anonymous

last 1

37. anonymous

thank you guys so so much for everything really

38. anonymous

$1/m ^{18}$

39. anonymous

you are hella smart with this you must have all good grades in math
