Answer 1

Step-by-step explanation:

find the value of √3+√5/3-√5 correct to the 3 significant figures

for that~

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 to find the value we need

   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

hope it helps you
