Question

Find value of a and b root 7 + root 6 upon root 7 - root 6 = a + root 42b​

Answer 1

Hey mate here is your answer

7+√6 =a+42b

7-√6

7+√6 x 7+√6 = a+42b

7-√6 7+√6

(7+√6)2. = a+ 42b

(7)2+(√6)2

(7)2 + (√6)2 + 2x 7 x √6 = a+42b

49- 6

49+6+14√6 = a+42b

43

45 +( 7)2√6 = a+42b

-------------------

43

45+√6x7

-------------- = a+42b

43

= 45 + √42

43. 43

so a = 45. and b = 1
