Problem: Group (mathematics):

Exchanging "+" and "" in the expression, i.e. permuting the two solutions of the equation can be viewed as a (very simple) group operation. Similar formulae are known for cubic and quartic equations, but do not exist in general for degree 5 and higher. Abstract properties of Galois groups associated with polynomials (in particular their solvability) give a criterion for polynomials that have all their solutions expressible by radicals, i.e. solutions expressible using solely addition, multiplication, and roots similar to the formula above.

What is an example of a complex operation?

A: unanswerable

Problem: Many kinds of clothing are designed to be ironed before they are worn to remove wrinkles. Most modern formal and semi-formal clothing is in this category (for example, dress shirts and suits). Ironed clothes are believed to look clean, fresh, and neat. Much contemporary casual clothing is made of knit materials that do not readily wrinkle, and do not require ironing. Some clothing is permanent press, having been treated with a coating (such as polytetrafluoroethylene) that suppresses wrinkles and creates a smooth appearance without ironing.
What material doesn't easily wrinkle?

Answer: knit

The Japanese enlarged administration and appointed local leaders, which weakened the authority of local traditional leaders. Japan also tried to change the social organization in the islands from Matrilineality to the Japanese Patriarchal system, but with no success. Moreover, during the 1930s, one third of all land up to the high water level was declared the property of the Japanese government. On the archipelago, before it banned foreign traders, the activities of Catholic and Protestant missionaries were allowed. Indigenous people were educated in Japanese schools, and studied Japanese language and Japanese culture. This policy was the government strategy not only in the Marshall Islands, but on all the other mandated territories in Micronesia. On March 27, 1933, Japan handed in its notice at the League of Nations, but continued to manage the islands, and in the late 1930s began building air bases on several atolls. The Marshall Islands were in an important geographical position, being the easternmost point in Japan's defensive ring at the beginning of World War II.
What was the traditional social organization of the Marshall Islanders?
A: Matrilineality

Context and question: Since 2002, the North East of the country has seen sectarian violence by Boko Haram, an Islamist movement that seeks to abolish the secular system of government and establish Sharia law. Nigerian President Goodluck Jonathan in May 2014 claimed that Boko Haram attacks have left at least 12,000 people dead and 8,000 people crippled. At the same time, neighbouring countries, Benin, Chad, Cameroon and Niger joined Nigeria in a united effort to combat Boko Haram in the aftermath of a world media highlighted kidnapping of 276 schoolgirls and the spread of Boko Haram attacks to these countries.
When did Boko Haram become active in Nigeria?
Answer: 2002

Question: The Britishby inclination as well as for practical reasonshad tended to avoid large-scale commitments of troops on the Continent. They sought to offset the disadvantage of this in Europe by allying themselves with one or more Continental powers whose interests were antithetical to those of their enemies, particularly France.:1516 By subsidising the armies of continental allies, Britain could turn London's enormous financial power to military advantage. In the Seven Years' War, the British chose as their principal partner the greatest general of the day, Frederick the Great of Prussia, then the rising power in central Europe, and paid Frederick substantial subsidies for his campaigns.:106 This was accomplished in the Diplomatic Revolution of 1756, in which Britain ended its long-standing alliance with Austria in favor of Prussia, leaving Austria to side with France. In marked contrast to France, Britain strove to prosecute the war actively in the colonies, taking full advantage of its naval power. :6466 The British pursued a dual strategy naval blockade and bombardment of enemy ports, and rapid movement of troops by sea. They harassed enemy shipping and attacked enemy colonies, frequently using colonists from nearby British colonies in the effort.
Is there an answer to this question: How did the British behave in defending their colonies compared to the French approach?

Answer: In marked contrast to France, Britain strove to prosecute the war actively in the colonies

In 1924, the Tajik Autonomous Soviet Socialist Republic was created as a part of Uzbekistan, but in 1929 the Tajik Soviet Socialist Republic (Tajik SSR) was made a separate constituent republic, however the predominantly ethnic Tajik cities of Samarkand and Bukhara remained in the Uzbek SSR. Between 1927 and 1934, collectivization of agriculture and a rapid expansion of cotton production took place, especially in the southern region. Soviet collectivization policy brought violence against peasants and forced resettlement occurred throughout Tajikistan. Consequently, some peasants fought collectivization and revived the Basmachi movement. Some small scale industrial development also occurred during this time along with the expansion of irrigation infrastructure.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What policy brought violence against the rich?
Ah, so..
unanswerable
