simplify ((-1)^n)/(3^n)

Solution

simplify

\frac{( - 1 ) ^{n}}{3 ^{n}}

Solution

(- \frac{1}{3})^{n}

Solution steps

\frac{( - 1 ) ^{n}}{3 ^{n}}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

\frac{( - 1 ) ^{n}}{3 ^{n}} = (\frac{- 1}{3})^{n}

= (\frac{- 1}{3})^{n}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= (- \frac{1}{3})^{n}
