If a and b are rational number 8 then find the value of a and b √3+√2/√3-√2=a+b√6 |
|
Answer» Step-by-step explanation:a and b are rational numbersThe value of a and bGiven,Taking the LHS of the equation,RATIONALISING the denominator by multiplying √3 + √2 on both numerator and denominator,SIMPLIFYING by using identities:(a + b)² = a² + b² + 2AB(a + b) × (a - b) = a² - b²But we know that,EQUATING it we get,a = 5b = 2Hence the value of a is 5 and value of b is 2. |
