Step 1.1

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$x^{3 - 4} y^{0}$

Step 1.2

Subtract $4$ from $3$ .

$x^{- 1} y^{0}$

Step 2

Simplify $x^{- 1} y^{0}$ .

$x^{- 1}$

Step 3

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{x}$
