Question

( frac{5+2 sqrt{3}}{7+4 sqrt{3}}=a-6 sqrt{3} )
Takey LHS
( frac{5+21 / 3}{7+4 sqrt{3}}left(frac{7-4 sqrt{3}}{7-4 sqrt{3}}right) )
( frac{35-20 sqrt{3}+14 sqrt{3}-8 times 3}{49-(16 times 3)} )
( x quad 35-24-6 sqrt{3} )
a ( 11-6 sqrt{3}=a-b sqrt{3} )
( a=a=11 quad b=6 )

# 5+213 – a b Jo a-b to 7+453
