Simplify x^4y^5*x^-6

$x^{4} y^{5} \cdot x^{- 6}$

Step 1

Multiply $x^{4}$ by $x^{- 6}$ by adding the exponents.

Move $x^{- 6}$ .

$x^{- 6} x^{4} y^{5}$

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

$x^{- 6 + 4} y^{5}$

Add $- 6$ and $4$ .

$x^{- 2} y^{5}$

Step 2

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

$\frac{1}{x^{2}} y^{5}$

Step 3

Combine $\frac{1}{x^{2}}$ and $y^{5}$ .

$\frac{y^{5}}{x^{2}}$
