simplify x^{-1}+x^{-1}

simplify

x^{- 1} + x^{- 1}

\frac{2}{x}

Solution steps

x^{- 1} + x^{- 1}

Add similar elements:

x^{- 1} + x^{- 1} = 2 x^{- 1}

= 2 x^{- 1}

Apply exponent rule:

a^{- 1} = \frac{1}{a}

x^{- 1} = \frac{1}{x}

= 2 \cdot \frac{1}{x}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{2 \cdot 1}{x}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{2}{x}

2 (\frac{5}{4})

1. 5^{2} + 1. 5^{2}

(x^{2} - 8) - 2

(r - 4) (r + 4)

\frac{1 + 2 3}{3 + 3}
