$\int 2 t^{- 10} d t$

Step 1

Since $2$ is constant with respect to $t$ , move $2$ out of the integral.

$2 \int t^{- 10} d t$

Step 2

By the Power Rule, the integral of $t^{- 10}$ with respect to $t$ is $- \frac{1}{9} t^{- 9}$ .

$2 (- \frac{1}{9} t^{- 9} + C)$

Step 3

Step 3.1.1

Combine $t^{- 9}$ and $\frac{1}{9}$ .

$2 (- \frac{t^{- 9}}{9} + C)$

Step 3.1.2

Move $t^{- 9}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$2 (- \frac{1}{9 t^{9}} + C)$

Step 3.2

Simplify.

$2 (- \frac{1}{9 t^{9}}) + C$

Step 3.3.1

Multiply $- 1$ by $2$ .

$- 2 \frac{1}{9 t^{9}} + C$

Step 3.3.2

Combine $- 2$ and $\frac{1}{9 t^{9}}$ .

$\frac{- 2}{9 t^{9}} + C$

Step 3.3.3

Move the negative in front of the fraction.

$- \frac{2}{9 t^{9}} + C$
