simplify 2x*x^{-1}

Solution

simplify

2 x \cdot x^{- 1}

Solution

2

Solution steps

2 x x^{- 1}

Apply exponent rule:

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

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

= 2 x^{1 - 1}

Subtract the numbers:

1 - 1 = 0

= 2 x^{0}

Apply exponent rule:

a^{0} = 1,

assuming

a \neq = 0

x^{0} = 1

= 2 \cdot 1

Multiply the numbers:

2 \cdot 1 = 2

= 2
