Answer:

Heya mate!! Here is ur answer...

Step-by-step explanation:

5+3 = a-b √15

2√5-3√3

Let's simplify L. H. S by rationalising it's denominator.

5+3

2√5-3√3

5+3 * 25+33

2√5-3√3 2√5+3√3

5(25+33)+3(25+33

(2√5)^2-(3√3)^2

10+315+215+9

20-27

19+515

-7

-19/7 + 5/7 √15

On comparing the result of L. H. S from R. H. S we get

a=-19/7 and b=5/7

May this help uh!!

Answer:

√5+√3 = a-b √15

2√5-3√3

Let's simplify L. H. S by rationalising it's denominator.

√5+√3

2√5-3√3

√5+√3 * 2√5+3√3

2√5-3√3 2√5+3√3

√5(2√5+3√3)+√3(2√5+3√3

(2√5)^2-(3√3)^2

10+3√15+2√15+9

20-27

19+5√15

-7

-19/7 + 5/7 √15

On comparing the result of L. H. S from R. H. S we get

a=-19/7 and b=5/7
