simplify x*x^{-2}

Solution

simplify

x \cdot x^{- 2}

Solution

\frac{1}{x}

Solution steps

x x^{- 2}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

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

= x^{1 - 2}

Subtract the numbers:

1 - 2 = - 1

= x^{- 1}

Apply exponent rule:

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

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

= \frac{1}{x}

Popular Examples

(y-1)/4-(2y+5)/3 = 1/6

\frac{y - 1}{4} - \frac{2 y + 5}{3} = \frac{1}{6}

factor 6x^2+23x+20 factor

6 x^{2} + 23 x + 20

x (x + 4) \leq 0

simplify (n^2-n-12)/(n^2-4n)simplify

\frac{n ^{2} - n - 12}{n ^{2} - 4 n}
