simplify x^1*x^{-1}

Solution

simplify

x^{1} \cdot x^{- 1}

Solution

1

Solution steps

x^{1} x^{- 1}

Apply exponent rule:

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

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

= x^{1 - 1}

Subtract the numbers:

1 - 1 = 0

= x^{0}

Apply exponent rule:

a^{0} = 1,

assuming

a \neq = 0

= 1
