求解步骤

(n^{2} + n + 5)^{10}

(n^{2} + n + 5)^{10} = (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5)

= (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5) (n^{2} + n + 5)

乘开
