Step-by-step explanation:
hey dude here is your answer
L.H.S, = 5+3√3 × 7-4√3
7+4√3 × 7-4√3
cross multiple in numerator and use a²-b² identity in denominator
= (5×7)+(3√3×7)-(5×4√3)-(3√3×4√3)
(7)² - (4√3)²
= 35+21√3-20√3-12×3
49-16×3
= 35+√3-36
49-48
= √3-1
1
=√3-1 or 1-√3
.
.
a+b√3 =1-√3
√3 and √3 will be cancelled
a+b=1
HOPE IT HELPS YOU
