Evaluate (x^3x^-4yy)/1

$\frac{x^{3} x^{- 4} y \cdot y}{1}$

Multiply $x^{3}$ by $x^{- 4}$ by adding the exponents.

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

$\frac{x^{3 - 4} y \cdot y}{1}$

Subtract $4$ from $3$ .

$\frac{x^{- 1} y \cdot y}{1}$

Multiply $y$ by $y$ by adding the exponents.

Move $y$ .

$\frac{x^{- 1} (y \cdot y)}{1}$

Multiply $y$ by $y$ .

$\frac{x^{- 1} y^{2}}{1}$

Move $x^{- 1}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{y^{2}}{x}$
