Question

if 3+√7 3−√7 + 3−√7 3+√7 = + √7 find the value of a and b​

Answer 1

Answer:

We have been given that 3+√7/3-√7 = a+b√7. Inorder to rationalize this, we need yo multiply by 3+√7 in both numerator and denominator. Now, on comparing both sides, we get a = 8 and b = 3. Therefore, a = 8 and b = 3.
