use either the multiples method or the prime factors method to find the least common multiple of 6 and 20

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

What is the solution of log2  (3x  -  7)  =  3? 4 5

Which expression gives you the distance between the points (5,1)and(9,-6)
