Work Step by Step

Write $96$ as $16(6)$ to obtain: $=\sqrt[4]{16(6)x^{11}} \\=\sqrt[4]{2^4(6)x^{11}}$ RECALL: $\sqrt[n]{a^n}=a$ Factor the radicand (expression inside the radical sign) so that at least one factor is a perfect fourth power, and then use the rule above to simplify and obtain: $=\sqrt[4]{(2^4x^8) \cdot 6x^3} \\=\sqrt[4]{2^4(x^2)^4 \cdot 6x^3} \\=2x^2\sqrt[4]{6x^3}$
