Answer 6

Its not in scientific notation tho

Answer 7

\[0.00001578\] in scientific notation
\[\huge 1.578\times 10^{-5}\]

Answer 8

o, lml

Answer 9

i moved the decimal and counted the spaces
since it went left, the exponent is negative

Answer 10

i mean right

Answer 11

right

Answer 12

that is the answer to question one

Answer 13

ready for part two?

Answer 14

not yet, i have to take away what I had for one then put in whats rite! :P

Answer 17

ok! lol, i done

Answer 18

ok ready?

Answer 19

yes ma'am!

Answer 20

deposit another quarter

Answer 21

for the next one we have to divide

Answer 22

quick question

Answer 23

\[\huge \frac{2.5\times 10^4}{1.578\times 10^{-5}}\]

Answer 24

ok

Answer 25

did we round the 1st to the nearest 10th?

Answer 26

we rounded a bit, perhaps we should round some more

Answer 27

we can't really round to the nearest tenth, i think that is a typo
our number had a zero in the tenths place

Answer 28

ooo, ok

Answer 29

maybe they meant round this \[\huge 1.578\times 10^{-5}\] to this \[\huge 1.6\times 10^{-5}\]

Answer 30

that would make life easier

Answer 31

mkay

Answer 32

lol

Answer 33

then the second question we can do \[\frac{2.5\times10^4}{1.6\times 10^{-5}}\]

Answer 34

\[2.5\div 1.6=1.5625\] and \[\frac{10^4}{10^{-5}}=10^{4-(-5)}=10^9\]

Answer 35

so we have
\[1.5625\times 10^9\] as our answer
again maybe you should round or you can leave it like that

Answer 36

lets round... it said round again

Answer 37

1.6 x 10^9

Answer 38

right?

Answer 39

ok

Answer 40

that is the answer to number 2

Answer 41

a billion has 9 zeros

Answer 42

okay... 1 more! YESS! :P

Answer 43

so 7.046 billion is \(7.046\times 10^9\)
that is bigger than \(1.6\times 10^9\)

Answer 44

oh wait i misread the question sorry

Answer 45

rite

Answer 46

o, ok, lol

Answer 47

last job it so divide again \[\frac{7.046\times 10^9}{1.6\times 10^9}\]

Answer 48

about \(4.4\)

Answer 49

and now we are done!!

Answer 50
