-2v3 + v75
Lena [83]

Answer:

a)      3\sqrt{3}

Step-by-step explanation:

Step(i):-

Given     - 2 √3 + √75

     we know that        25 × 3 = 75

                 - 2 √3 + √75    

            =    -2 √3 + \sqrt{25 X 3}

By using

       \sqrt{ab} = \sqrt{a}  \sqrt{b}

          =  -2\sqrt{3} + \sqrt{25} X \sqrt{3}

         =  -2\sqrt{3} + 5  \sqrt{3}

        = (-2 + 5 ) \sqrt{3}

       = 3\sqrt{3}
