Question

exponents??
simplify this so i can finish a word problem?
1^-0010

Answer 1

Type it into a calculator?

Answer 2

1 to the power of anything is always 1.

Answer 3

it wouldnt let me put two 0's next to eachother when their not a decimal. and haha, you're right about the power, oops wasnt thinking.

Answer 4

okay whats 1^-0010 x 10? is it 10?

Answer 5

Yes. 1^0010=1x10=10

Answer 6

it just doesnt sound right for the problem. the problem is 1000x10^-10.

Answer 7

Well that changes things.

Answer 8

1000.
Move the (.) 10 places to the left.
.0000001000

Answer 9

ok.
.0000001000 x 10^-10

Answer 10

No.
1000x10^-10=.0000001000

Answer 11

noo its not scientific notation. its actually like seperate numbers being multiplied.
"An x-ray length is 10^-10 m. An ultraviolet wave is ten times the wavelength of an x-ray. Find the wavelength of ultraviolet waves."

Answer 12

Im mean 1000 times larger*******

Answer 13

10^-10 x 1000
100 = 10^3

so
10^-10 x 10^3

add exponents...

10^-7 m

Answer 14

10−7 meters. That is:
1×10−7 m

Then you're told that visible light has wavelengths such as
3.8×10−7m
and
7.6×10−7 m

Clearly therefore, because 3.8 > 1 and 7.6 > 1, visible light has a longer wavelength.

Answer 15

Better?

Answer 16

so what am I supposed to write down?

Answer 17

I guess all of it. I don't think I'm in that class so to be safe I would write it all...

Answer 18

but visible ight has nothng to do with anything. unless that eans ultra violet waves?

Answer 19

Do you have a part b.?

Answer 20

That says this?
b. The wavelengths of visible light are between 3.8 x 10^(-7) m and 7.6 x 10^(-7) m. Are these wavelengths longer or shorter than the ultraviolet rays? Explain.

Answer 21

If not ignore the second equation thing I gave you and only write down the first one.
