Answer 2

ok, tis to simplify?

Answer 3

3x

Answer 4

was wondering that too

$$(3x10^6)(6x10^{-8}) or (3\times10^6)(6\times10^{-8})$$?

Answer 6

thats what it looks like ...

Answer 7

expand it first
what do you get ?

Answer 8

that's "times" no "x :/

Answer 9

Shes right

Answer 10

because they want an answer in scientific notation

Answer 11

i keep getting 18 x 10^14 -_-

Answer 12

is not an "x" literal, is a multiplication operator :/

Answer 13

@beautifullife ,so if it was an "x", your answer is close, it'd be \(18x^{-14}\)

Answer 14

huh, I get that too

Answer 15

but that's not an option....

Answer 16

yes, it's not because is not an "x" literal, is a "times" :/

Answer 17

im so confused

Answer 18

what you have is really just

\( \huge (3\times10^{-6})(6\times10^{-8})\)

Answer 19

\(10^{-1} = 0.1, 10^{-2} = 0.01, 10^{-5} = 0.00001\) and so on

Answer 20

anyhow, so you'd end up with 18 and a \(10^{-14}\)

Answer 21

now,
$$
\cfrac{18}{10}\times 10 = 18 \implies 1.8 \times 10^1 = 18\\
1.8 \times 10^1\times 10^{-14} \implies \large ?
$$

Answer 22

i dont understand that bc its not anoption

Answer 23

I think your thing has a mistake

Answer 24

so call the school?!?!?!?!

Answer 25

@beautifullife did you see my posting?

Answer 26

oh sorry no i didn't @jdoe0001 ill check it now

Answer 27

$$
\cfrac{\color{red}{18}}{10}\times 10 = \color{red}{18} \implies \color{blue}{1.8} \times 10^1 = \color{red}{18}\\
\color{blue}{1.8} \times 10^1\times 10^{-14} \implies \large ?
$$

Answer 28

wait so the answer is 1.8 x 10 -15
bc you add the exponents

Answer 29

yes, you add the exponents, what's +1-14?

Answer 30

-13

Answer 31

so its not 10^-15 its 10^-13

Answer 32

yes

Answer 33

thanks

Answer 34

yw

Answer 35

wait

Answer 36

Answer 37

Answer 38

right
