**first correct answer gets a brainliest**

what is the absolute value of the complex number − 4 + 3i ?

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

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?
