Question 170841: One common use of positive and negative exponents is in writing numbers as scientific notation. for example 0.000052 can be writtrn as 5.2*10^-5. A) Use scientific notation and the law of exponents to evaluate (0.000054)(0.00000033)(0.013). Leave your answer in scientific notation. B) If a space probe travels at 12 kilometers per second for 10 years, how far will it travel? Write your answer in scientific notation. ( Assume 1 year =365)
Scientific Notation: A number is expressed in scientific notation when it is in the form a*10^n, where a is greater than or equal to 1 but less than 10 and n is an integer.
I got the first part, I think.
5.4*10^-5
3.3*10^-7
1.3*10^-2= 23.17*10^-14
The second part I have no clue.
