Answer 2

Given:

$\frac{5 \: + \: 2 \: \sqrt{3} }{7 \: + \: 4 \: \sqrt{ 3} }$

STEP BY STEP EXPLANATION:

$(5 \: + \: 2 \: \sqrt{3} ) \times (7 - 4 \sqrt{3} ) - a \: - \sqrt{3} \: b$

Multiply the parentheses

$35 \: - \: 20 \sqrt{3} \: + \: 14 \sqrt{3} - 24 \: - a \: \sqrt{3} \: b$

Subtract collect like terms

$<font color = red>$

$11 - 6 \sqrt{3} \: - a \: - \sqrt{3} \: b$

$<font color = black>$

Hence verified !
