Question

Find the value of a and b if 6-4√3/6+4√3 =a+b√3​

Answer 1

Answer:

Step-by-step explanation:

= 6-4√3/6+4√3 =a+b√3​

= After rationalising

=  6-4√3/6+4√3* 6-4√3/6-4√3

= (6-4√3)^2 / (6+4√3)(6-4√3)

= 36+48-48√3/ 36- 48

= 84-48√3/12

= After cutting

= 7- 4√3 = a+b√3​

= after putting value

= a= 7 b= -4
