解

簡約

3 (cos (x) + 4)

3 cos (x) + 12

解答ステップ

3 (cos (x) + 4)

拡張

3 (cos (x) + 4) : 3 cos (x) + 12

= 3 cos (x) + 12

e x p an d w^{\frac{3}{7}} (w^{\frac{4}{7}} + 5 w^{\frac{18}{7}})

e x p an d \frac{sin ( x )}{x ( x + 1 )}

e x p an d 3 (1 + \frac{2}{n} i)^{2}

e x p an d (n + 7) lo g_{7} (x)
