Question

China's population is 14.46 *10^8. Marshall Islands population is 602.5*10^2. How many times larger is china population than marshalls islands population? Enter your answer using scientific notation

Answer 1

This is basic subtraction. To find the difference between 2 numbers, you subtract them.

Answer 2

It is definitely not subtraction

Answer 3

To find the difference you actually divide

Answer 4

@jackthegreatest can you help me (:

Answer 5

Well it says "How many ONES larger" so if whatever that means.
IF it means how MUCH larger, it's subtraction.
IF it means how many TIMES larger, it's division.

Answer 6

I actually messed up writing the question it's how many times larger

Answer 7

Answer 8

Can someone help me (:

Answer 9

\(\huge \frac{14.46 \times 10^8}{602.5\times 10^2} = \frac{14.46}{602.5}\times\frac{10^8}{10^2}=?\)

Does that help?

Answer 10

i know how to set it up im just confused on how to actually solve it

Answer 11

ok so you're confused on dividing 10^8 by 10^2?

Answer 12

well not exactly wouldnt u have to change the powers 10^8 and 10^2 because 14.46 and 602.5 arent in scientfic notation

Answer 13

they do not need to be

Answer 14

so then it would be 1.446 and 6.025 and the powers would be 9 and 4

Answer 15

oh really ?

Answer 16

then what do i do subtract the powers or add them

Answer 17

dividing means you subtract the powers. So \(\large 10^{8-2}\)

Answer 18

subtract

Answer 19

^^

Answer 20

then what with the decimals just divide them just like that even with the decimal in that spot?

Answer 21

yes. Tell me what you get from 14.46/602.5

Answer 22

so then it would be 0.024 right?

Answer 23

so the answer is 0.0024 10^6

Answer 24

yep. So you get \(\Large 0.024 \times 10^{6}\)

But there is still more to be done

Answer 25

didnt mean to add 2 zeros

Answer 26

Now you need to conver 0.024 to scientific notation

Answer 27

2.4 ?

Answer 28

yep, how many powers of 10 were needed

Answer 29

yes. 2.4 times what htough?

Answer 30

2

Answer 31

yep

Answer 32

Almost. -2

Answer 33

10^6-2 ...

Answer 34

oh okay

Answer 35

So You get \(\large 2.4\times 10^{6-2}\)

Answer 36

^^

Answer 37

thats the answr or do i change it again haha

Answer 38

10^4

Answer 39

10^4

Answer 40

well
2.4 x 10^4

Answer 41

yes

Answer 42

well yeah haha of course like that

Answer 43

can you help me with one more?

Answer 44

i have 5 min haha sure

Answer 45

repost...

What is the simplified form of this expression, written in scientific notation?

(3.276×10^5)×400,000÷(3.9×10^6)

Answer 48

can you help me @StudyGurl14

Answer 49

can you post this in a new thread? this thread is long and my computer is slow :/
