Question

Rationalize and simplify the values :

4/root 5 +root 3

Root 5 = 2.236 and root 3 = 1.732

Answer 1

firstly multiply denominator and numerator by root 5 minus under root 3

putting the value of root 5 and root 3 which is given

Answer 2

To rationalise 4/root5:
4/root5 x root5/root5 = 4 x root5 / 5

So, 4 x root5/ 5 + root3 =
4 x root5 + 5 x root3/ 5
=> 4(2.236) + 5(1.732)/5
=> 8.944 + 8.66/5
=> 3.5208
