Step-by-step explanation:
Question:—
- If √5+√6/√5-√6 = a+b√30, then find the value of a and b ?
To find:—
- the value of a and b ?
Solution:—
Let's solve the given problem
We have,
The denominator is √5-√6. Multiplying the numerator and denomination by √5+√6, we get
⬤ Applying Algebraic Identity
- (a+b)(a+b) = (a+b)² = a² + b² + 2ab to the numerator and
- (a-b)(a+b) = a² - b² to the denominator
We get,
On comparing the value of
a = 11 and b = 2
Answer:—
- Hence, the value of a = 11 and b = 2
Used Formulae:—
- a+b)(a+b) = (a+b)² = a² + b² + 2ab
- (a-b)(a+b) = a² - b²
