√x*√-x имеет смысл только при х равном нулю.

т.к. х и -х противоположны, а под корнем четной степени могут стоять только неотрицательные значения.

Princess of Wales

Lady Diana Frances Spencer, (Diana Frances Mountbatten-Windsor, nee Spencer)
(July 1, 1961–August 31, 1997) was the first wife of Charles, Prince of Wales.
From her marriage in 1981 to her divorce in 1996 she was styled "Her Royal
Highness The Princess of Wales". After her divorce from the Prince of
Wales in 1996 Diana ceased to be the Princess of Wales and also lost the
resulting Royal Highness style,[1] She received the title normally used by the
ex-wives of peers, Diana, Princess of Wales under Letters Patent issued by
Queen Elizabeth II at the time of the divorce.Diana was often called Princess
Diana by the media and the public, but she did not possess such a title and was
not personally a princess, a point Diana herself made to people who referred to
her as such. Contrary to belief, being Princess of Wales does not make one a
princess in one's own right. It merely indicates that one was married to a
Prince of Wales. Princesses in their own right only exist by creation of the
monarch or by birth. Diana was in fact the first non-princess to be Princess of
Wales for centuries. Previous Princesses of Wales, such as Alexandra of Denmark
or Mary of Teck were already princesses by birth when they married a Prince of
Wales.
