Question

simplify (number system chapter)

​

Answer 1

Step-by-step explanation:

2 +√3 + 2-√3 + √3-1

2-√3 2+√3 √3+1

= {(2+√3)(√3+1)(2+√3) + (2-√3)(√3+1)(2-√3) + (2-√3)(2+√3)(√3+1)

(2-√3)(2+√3)(√3+1)

= { (4+2√3+2√3+3)(√3+1)+ (4-2√3-2√3+3)(√3+1)+(4-3)(√3+1)}/(2-√3)(2+√3)(√3+1)

= {(7+4√3)(√3+1) + (7-4√3)(√3+1)+1(√3+1)

(2-√3)(2+√3)(√3+1)

= (√3+1){7+4√3+7 -4√3 +1)

(2-√3)(2+√3)(√3+1)

= 7+4√3+7-4√3 +1

(2-√3)(2+√3)

= 14 + 1

4-3

= 15
