PLEASE HELP
medical xrays, with a wavelength of about 10^10m, can penetrate completely through your skin.
Ultra violet rays, which cause sunburns by penetrating only the top level of skin, have a wavelength about 1000 times the wavelength of an xray. find the wavelength of ultraviolet rays. show your work.
Hint: scientific notation.

Best ResponseYou've already chosen the best response.0I HAVE USED THE PROPERTY : M ^n * M ^ b = M ^(n+b)

Best ResponseYou've already chosen the best response.0but why do you need 10^3? where does it come from in the problem?

Best ResponseYou've already chosen the best response.0wouldnt that be 1 x 10^3?

Best ResponseYou've already chosen the best response.1\[10^3=1 \times 10^3\]

Best ResponseYou've already chosen the best response.0so thats how i get the 10+3?

Best ResponseYou've already chosen the best response.0now u understand what i was trying to say

Best ResponseYou've already chosen the best response.0so it would be (1 x 10^10)(1 x 10^3) ? which simplifies to 1 x 10^7?
