E=\sqrt[32]{1+80(9^2+1)(9^4+1)(9^8+1)}

解答

E = 32 1 + 80 (9^{2} + 1) (9^{4} + 1) (9^{8} + 1)

E = 32 1.85302 E 15

十进制

E = 3

求解步骤

E = 32 1 + 80 (9^{2} + 1) (9^{4} + 1) (9^{8} + 1)

化简

32 1 + 80 (9^{2} + 1) (9^{4} + 1) (9^{8} + 1) : 32 1.85302 E 15

E = 32 1.85302 E 15

5 x + 12 = 2 x - 8

2 (1 - x) + 2 = - x + \frac{1}{2} (2 - x) + x + \frac{4}{2}

so l v e f or x, m x - n y = m^{2} + n^{2}

5 x - (2 x + 4) = (3 x + 1) - (2 x - 3)

so l v e f or x, \frac{1}{4} y = 14 x
