[-2\5]^-3 - [-5\2]^-2

What is the distance between the points 4,10 and -3,-14 on the coordinate plane

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

You can find the constant of proportionality by finding the ratio of
