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.

no i was going with 1000 x 10^10 but thats not right.

now just ensure you report answer in scientific notation

i have just use the scientific notation form

I HAVE USED THE PROPERTY : M ^n * M ^ b = M ^(n+b)

manishsatywaliBest ResponseYou've already chosen the best response.0
here M = 10 and n = 3 , b = 10

did u get that ?

10^3 * 10^(10)
 one year ago

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

minimooBest ResponseYou've already chosen the best response.0
wouldnt that be 1 x 10^3?
 one year ago

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

@AravindG IS RIGHT DO U FOLLOW HIM NOW ?

minimooBest ResponseYou've already chosen the best response.0
so thats how i get the 10+3?
 one year ago

manishsatywaliBest ResponseYou've already chosen the best response.0
now u understand what i was trying to say
 one year ago

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