Answer:
a = 9 and b = 6
Step-by-step explanation:
Left Hand Side
5+2[tex]\sqrt{3}[/tex]/ 7+ 4[tex]\sqrt{3}[/tex]
We rationalise the denominator by multiplying both the numerator and denominator by a rationalising factor in this case we use 7 - 4 [tex]\sqrt{3}[/tex].
5+2 [tex]\sqrt{3}[/tex] x 7 - 4 [tex]\sqrt{3}[/tex]

7+4[tex]\sqrt{3}[/tex] x 7 - 4 [tex]\sqrt{3}[/tex]
35 + 14 [tex]\sqrt{3}[/tex] - 20[tex]\sqrt{3}[/tex] - 24
= ___________________
49-48
35-24+14[tex]\sqrt{3}[/tex]-20[tex]\sqrt{3}[/tex]

=9-6[tex]\sqrt{3}[/tex]
Given LHS = RHS
∴9-6[tex]\sqrt{3}[/tex] = a - b[tex]\sqrt{3}[/tex]
a = 9 and b = 6
Mark the best answer brainliest ;)
