Operamos.

$\mathrm{E=\sqrt[3]{\frac{19^{x+4}-19^{x-3} }{18 \times 19^x} } }\\\\\mathrm{Separamos~en~bases~iguales}\\\\\mathrm{E=\sqrt[3]{\frac{(19^x \times 19^+^4)-(19^x \times 19^3)}{18 \times 19^x} } }\\\\\mathrm{Factorizamos}\\\\\mathrm{E=\sqrt[3]{\frac{19^x(19^+^4-19^3)}{18 \times 19^x} } }\\\\\mathrm{Simplificamos}\\\\\mathrm{E=\sqrt[3]{\frac{(19^+^4-19^3)}{18} } }\\\\\mathrm{E=\sqrt[3]{\frac{(123462)}{18} } }\\\\\mathrm{E=\sqrt[3]{6859}}\\\\\Large\boxed{\mathbf{E=19}}$
