Answer 1

Step-by-step explanation:

We need to find the square root of 5 to two decimal places. So

        2.23

      --------------

  2    5

  2     4

      ---------------

 42    100

   2      84

       ----------------

443       1600

             1329

        ------------------

               271

So we get 2.23

Now we need to find the value of

   3 + √5 / 3 - √5

Rationalising the denominator we get

   3 + √5 / 3 - √5  x 3 + √5 / 3 + √5

     (3 + √5)^2 / 9 - 5

 9 + 5 + 6 √5 / 4

 14 + 6√5 / 4

 14 + 6 (2.23) / 4

6 .854

Answer 2

Answer:

√5=2.236

in question

√[3+√5/3-√5]

=√[3+2.236/3-2.236]

=6.85
