1. If a and B are two irrational numbers and a + B = 3, what are a and B respectively? 2. Let the certificate part of √ 3 be x and the decimal part be y, and find the value of the quadratic power of x-2y + 2 √ 3
First of all, the answer is not unique. For example, a = √ 3 + 1, B = - √ 3 + 2; a = √ 3 + 3, B = - √ 3
Second question:
x=1 y=√3-1
So x ^ 2-2y + 2 √ 3 = 1-2 * (√ 3-1) + 2 √ 3 = 3
