Question

(√5+√3)(3√3÷√5+√2−√3+√2)​

Answer 1

Step-by-step explanation:

The correct option is B

x = 13, y = -7

5−√32+√3=x+y√3

5−√32+√3=(5−√3)(2−√3)(2+√3)(2−√3)

                                              (Rationalising the denominator)

=10−5√3−2√3+3(2)2−(√3)2=13−7√34−3

=13−7√31=13−7√3

∴13−7√3=x+y√3

Comparing, we get

x = 13, y = -7
