Answer 2

Answer:

18

Step-by-step explanation:

The sum of each row of Pascal's triangle is a power of 2. In fact, the sum of the entries in the nth row is 2n.

In algebra, a triangle-shaped grouping of integers known as Pascal's triangle provides the coefficients for the expansion of any binomial formula, such as (x + y)n. Although it is much older, it bears the name of the French mathematician Blaise Pascal from the 17th century. In the eleventh century, the Chinese mathematician Jia Xian created a triangular representation for the coefficients. Yang Hui, a Chinese mathematician, is typically credited with popularising and furthering the study of this triangle, which is why it is sometimes referred to as the Yang Hui triangle in China. It was referred to as the "Old Method" and was presented as an illustration in Chinese mathematician Zhu Shijie's Siyuan yujian (1303; "Precious Mirror of Four Elements"). The Persians investigated the extraordinary pattern of coefficients in the 11th century.
