Question

Simplify the given question

Answer 1

Answer:

HEY THERE

Step-by-step explanation:

$\frac{2 + \sqrt{3} }{2 - \sqrt{3} } - \frac{2 - \sqrt{3} }{2 + \sqrt{3} }$

$\frac{(2 + \sqrt{3})^{2} - ( 2 - \sqrt{3} ) } { {2}^{2} - ( \sqrt{3}) ^{2} }$

$\frac{ {2}^{2} + ( \sqrt{3} ) ^{2} + 2 \times 2 \times \sqrt{3} - (( {2}^{2}) + ( \sqrt{3} ^{2}) - 2 \times 2 \times \sqrt{3} )}{4 - 3}$

$\frac{4 + 3 + 4 \sqrt{3} - (4 + 3 - 4 \sqrt{3} ) }{1}$

$7 + 4 \sqrt{3} - 7 + 4 \sqrt{3} \\ = 8 \sqrt{3}$ =8×1.732

answer => 13.856

HOPE IT HELP

identities used->

$(a + b)^{2} = {a}^{2} + {b}^{2} + 2ab$

$(a - b) ^{2} = {a}^{2} + {b}^{2} - 2ab$

${a}^{2} - {b}^{2} = (a + b)(a -b )$
