Question 875484: Express the number in normalized scientific notation:
0.003 x 10-2
Answer: 3.0 x 10^-5
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
your expression is:
.003 * 10^-2
the standard form would be 3.0 * 10 raised to an exponent.
in order to make 3.0 equivalent to .003, you have to divide it by 1000.
you get:
3 / 1000 = .003
this is the same as 3 * 1/1000 = .003
since 1/1000 equals 1/10^3 which is the same as 1 * 10^-3 which is the same as 10^-3, you get:
3 * 10^-3 = .003
your original expression is .003 * 10^-2
replace .003 with 3 * 10^-3 to get:
3 * 10^-3 * 10^-2 which is equal to 3 * 10^-3-2) which is equal to:
3 * 10^-5
you are correct.
confirm by using your calculator to get:
.003 * 10^-2 = .00003
3 * 10^-5 = .00003
actually my calculator said that .003 * 10^-2 = 3 * 10^-5.
it gave me the answer in scientific notation.
calculator do that sometimes.
