Answer 2

Answer:

see below ....

Step-by-step explanation:

Given Find the square root of 5 , correct to 2 decimal places . hence , find the value of √3+√5/3-√5 correct to the 3 significant figures

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
