Explain the the third question in detail...

Please answer

Answer 1

0.268

Step-by-step explanation:

√ ( 2-√3 ) ÷ √(2+√3)

rationalising by multiplying numerator and denominator by { √ (2-√3) }

we get,

=> { √ (2-√3) × √ (2-√3) } ÷ { √(2+√3) × √(2-√3)}

=> { √ (2-√3)² } ÷ { √ ( 2²-(√3)² ) }

=> (2-√3) ÷ { √ (4-3) }

=> (2-√3) ÷ √(1)

=> (2-√3)

=> 2-1.732

=> 0.268
