plaz help me bro ok ​

Answer 1

Answer:

Step-by-step explanation:

√3-1/√3+1=a+b√3

rationalizing the denominator;

√3-1/√3+1×√3-1/√3-1=a+b√3

3-√3-√3+1/3-1=a+b√3

4-2√3/2=a+b√3

4/2+{-2√3/2}=a+b√3

1/2+{-√3}=a+b√3

hence the value of a =1/2

                               b= -1

Answer 2

Answer:

1. $(\sqrt{3} - 1) \div ( \sqrt{3} + 1) \\ ( \sqrt{3} - 1) \times (\sqrt{3} - 1) \div ( \sqrt{3} - 1) \times ( \sqrt{3} + 1) \\ (3 + 1 - 2 \sqrt{3} ) \\ (3 - 1) \\ (4 - 2 \sqrt{3} ) \div 2 \\ 2 - \sqrt{3} = a + b \sqrt{3} \\ hence a = 2 \\ b = - 1$
