8.6: Power Series - Mathematics LibreTexts
WEBDec 21, 2020 · Recall that \(f(x) = \sum\limits_{n=0}^\infty x^n\) in Example 8.6.3 is a geometric series. According to Theorem 60, this series converges to \(1/(1-x)\) when \(|x|<1\). Thus we can say \[ f(x) = \sum\limits_{n=0}^\infty x^n = \frac 1{1

Basic rules for exponentiation - Math Insight
WEBBasic rules for exponentiation. If n is a positive integer and x is any real number, then xn corresponds to repeated multiplication xn = x × x × ⋯ × x ⏟ n times. We can call this “ x raised to the power of n ,” “ x to the power of n ,” or simply “ x to the n .” Here, x is the base and n is the exponent or the power.
