X1的Word格式: = -(-1 + 1/(2 sqrt(30/(-40 + (1295852975 - 15sqrt(7227689318907585))^(1/3) + (5 (259170595 + 3sqrt(7227689318907585)))^(1/3)))) - 1/2 sqrt(-8/3 - 1/30 (1295852975 - 15 sqrt(7227689318907585))^(1/3)- (259170595 + 3 sqrt(7227689318907585))^(1/3)/(6 5^(2/3)) + 625 sqrt(30/(-40 +(1295852975 - 15 sqrt(7227689318907585))^(1/3) + (5 (259170595 + 3sqrt(7227689318907585)))^(1/3)))))^(1/5)
注:根式解精确无误!数值解仅作参考!因为,不同的数学软件给出的数值计算精度都不一样,大约在“小数点后万亿位”就不相同了。
