Evaluate

$$x^{26}$$

Solution Steps

Calculate \sqrt{x^{4}} to the power of 2 and get x^{4}.

$$x^{4}\left(\sqrt{x^{8}}\right)^{2}\left(\sqrt{x^{14}}\right)^{2}$$

Calculate \sqrt{x^{8}} to the power of 2 and get x^{8}.

$$x^{4}x^{8}\left(\sqrt{x^{14}}\right)^{2}$$

To multiply powers of the same base, add their exponents. Add 4 and 8 to get 12.

$$x^{12}\left(\sqrt{x^{14}}\right)^{2}$$

Calculate \sqrt{x^{14}} to the power of 2 and get x^{14}.

$$x^{12}x^{14}$$

To multiply powers of the same base, add their exponents. Add 12 and 14 to get 26.

$$x^{26}$$

Differentiate w.r.t. x
