The angstrom ( 1 Å=10^10 m) is a convenient metric unit for atomic measurements of length IT IS NOT AN IS UNIT The most commonly used SI unit for atomic measurements is the picometer (1 pm = 10^12 m; Example 18 Let A = { 1, 2, 3, 4, 5, 6}, B = { 2, 4, 6, 8 } Find A – B and B – A A – B = A – (A ∩ B) A ∩ B = {1, 2, 3, 4, 5, 6} ∩ {2, 4, 6, 8} = {2, 42 Find all values of C such that 3^2c1=28*3^c9 If you find more than one value of, then list your values in increasing order, separated by commas
