Simplify -2n^-2*(-n)

$- 2 n^{- 2} \cdot (- n)$

Rewrite using the commutative property of multiplication.

$- 2 \cdot - 1 n^{- 2} n$

Multiply $n^{- 2}$ by $n$ by adding the exponents.

Move $n$ .

$- 2 \cdot - 1 (n \cdot n^{- 2})$

Multiply $n$ by $n^{- 2}$ .

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

$- 2 \cdot - 1 (n^{1} n^{- 2})$

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

$- 2 \cdot - 1 n^{1 - 2}$

Subtract $2$ from $1$ .

$- 2 \cdot - 1 n^{- 1}$

Multiply $- 2$ by $- 1$ .

$2 n^{- 1}$

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

$2 \frac{1}{n}$

Combine $2$ and $\frac{1}{n}$ .

$\frac{2}{n}$
