## Tabbiejack 2 years ago Find the simplified form of the expression. Give your answer in scientific notation. (9x10^5) (6x10^-7)

$5.1*10^{-1}$

2. Tabbiejack

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

sorry it is 5.4

4. Tabbiejack

can you help me with another

yes

6. Tabbiejack

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

is it m

8. Tabbiejack

yes

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

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

11. Tabbiejack

o that is not the answer right

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

just remove1/4

14. Tabbiejack

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

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

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

|dw:1369551670166:dw|

19. Tabbiejack

and|dw:1369551862560:dw|

|dw:1369551868497:dw|

21. Tabbiejack

thats not an option

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. Tabbiejack

dah wow ok i was lost

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

its ok

27. Tabbiejack

i see know

28. Tabbiejack

I have another

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. Tabbiejack

i think its c

32. Tabbiejack

idk

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

34. Tabbiejack

really i got it right wow

35. Tabbiejack

last 1

37. Tabbiejack

thank you guys so so much for everything really

$1/m ^{18}$

39. Tabbiejack

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