$$54x^{8}$$

Steps Using Definition of a Derivative

To multiply powers of the same base, add their exponents. Add 2 and 7 to get 9.

$$\frac{\mathrm{d}}{\mathrm{d}x}(2x^{9}\times 3)$$

Multiply 2 and 3 to get 6.

$$\frac{\mathrm{d}}{\mathrm{d}x}(6x^{9})$$

The derivative of ax^{n} is nax^{n-1}.

$$9\times 6x^{9-1}$$

Multiply 9 times 6.

$$54x^{9-1}$$

Subtract 1 from 9.

$$54x^{8}$$
