(4)の文の和訳をしていただきたいです。 解説もお願いします！！ signedは誤りを訂正する問題でto signです。

1) It was careless for her to make such a mistake. 2) The meeting is to hold in London next month. 3) The girls soon got used to row the boat. 4) They got the old man signed the form.

下写真のように近似できるのは何故でしょうか？ 元のサイト↓ https://juken-mikata.net/how-to/mathematics/approximation-formula.html/amp

解答・解説: 1 {a+x²} = { a+x+ 3 ですから、 (1+x)} = 1+1/2x 3 と、近似できます。

However, (1). the concept of people viewing beauty differently from their own points of view has been around in most cultures of the world since ancient times. But what exactly is beauty, and is it really subjective? The definition in the Merriam-Webster dictionary is "the qualities in a person or a thing that give pleasure to the senses or the mind." This definition, however, does not mention whether there is a universal standard for beauty, or whether each individual person views beauty based on a totally different set of standards. Some of the arts seem to suggest the (2) if we consider the fact that everybody has their own favorite piece of music or painting that they consider to be beautiful. Nature, on the other hand, consistently comes up with scenes that are universally considered to be beautiful.
