Answer:
5+2√3
7+4√3
Open in answr app 7
=a+b√3
Since rationalization of
c-√d
Taking L.H.S. By rationalization,
a+√b a+√b c + √d X
c+√d
5+2√3 5+2√3 7-4√3 = 7+4√3 7+4√3 7-4√3
Since, {(a + b)(a − b) = a² — b²}
(5+2√3) x (7- 4√3) [(7)² - (4√3)²]
35+14√3-20√3-8√3√3 49-16√3 3
35-√3(148) - 24 49-48
35-√3(6) - 24 1
=11-6√3
Hence, by comparing a = 11 & b = -6.
