Simplify (y^-3)/y

$\frac{y^{- 3}}{y}$

Step 1

Move $y^{- 3}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{y \cdot y^{3}}$

Step 2

Multiply $y$ by $y^{3}$ by adding the exponents.

Multiply $y$ by $y^{3}$ .

Raise $y$ to the power of $1$ .

$\frac{1}{y^{1} y^{3}}$

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

$\frac{1}{y^{1 + 3}}$

Add $1$ and $3$ .

$\frac{1}{y^{4}}$
