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

$5.1*10^{-1}$

2. Tabbiejack Group Title

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

sorry it is 5.4

4. Tabbiejack Group Title

can you help me with another

yes

6. Tabbiejack Group Title

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

is it m

8. Tabbiejack Group Title

yes

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

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

11. Tabbiejack Group Title

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 Group Title

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

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 Group Title

i think its c

32. Tabbiejack Group Title

idk

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

34. Tabbiejack Group Title

really i got it right wow
