Rewrite the statement using a number in scientific notation.
1) the number of different eight character passwords that can be made with 26 letters and 10 numerals is approximately 2.8 trillion.
2) a beam of light can travel the length of a football field in about 30 nanoseconds. Express your answer in seconds.
Ps- I know that nano means one billionth but im still lost
+37095 2.8 trillion = 2,800,000,000,000 = 2.8 x 10^12 passwords
30 nanoseconds = .000 000 030 seconds = 3 x 10^(-8)
You can use the calculator to do this enter 30 divided by 1 000 000 000 then = and = again ....
