Answer:
a= 5 b=2
Step-by-step explanation:
Given:
(√3+√2)/(√3-√2) =a+b√6
Multiplying numerator and denominator of LHS with (√3+√2) we get―
=(√3+√2)(√3+√2)/[(√3-√2)(√3+√2)]
=[(√3+√2)^2]/(3-2) [using (a+b)(a-b)=a^2-b^2]
=(3+2+2√6)/1
=5+√6
On comparision with a+b√6, we see–
a=5 and b=2

Correct Question:
To find:
The value of a and b.
Solution:
Just rationalize the denominator of L.H.S term and we will get the answer...
Comparing the R.H.S from L.H.S I get,
a = 5 and b√6 = 2√6 i.e b = 2
