Question

Find a & b if a+b root15 = root5 +root3/root5 - root3

Answer 1

Step-by-step explanation:

√5+√3 =. a+b√15

√5-√3

rationalize denominatior

√5+√3 X √5+√3. = a+b√15

√5-√3. √5+√3

( √5+√3)^2. =. a+b√15

(√5)^2 -(√3)^2

(5 +3+ 2√15) / 2. = a+b√15

8/2 + 2/2(√15) = a+b√15

4+ √15. =. a+b√15

then....... a = 4. & b =1
