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

Answer»

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

...... HOPE it's HELPFUL
