= \frac{1 - ln ^{3} ( x ) \cdot \int - \frac{l n ( x ) + 3}{x l n ^{4} ( x )} d x}{ln ^{3} ( x )}_{0}^{0.5}

\int - \frac{ln ( x ) + 3}{x ln ^{4} ( x )} d x = \frac{1}{2 ln ^{2} ( x )} + \frac{1}{ln ^{3} ( x )}

= \frac{1 - ln ^{3} ( x ) ( \frac{1}{2 l n ^{2} ( x )} + \frac{1}{l n ^{3} ( x )} )}{ln ^{3} ( x )}_{0}^{0.5}

\frac{1 - ln ^{3} ( x ) ( \frac{1}{2 l n ^{2} ( x )} + \frac{1}{l n ^{3} ( x )} )}{ln ^{3} ( x )} = - \frac{0.5}{ln ^{2} ( x )}

= [- \frac{0.5}{ln ^{2} ( x )}]_{0}^{0.5}
