Answer:
(7+3
5
)/(7–3
5
)
Let us rationalize the denominator, we get
(7+3
5
)/(7–3
5
)=[(7+3
5
)(7+3
5
)]/[(7–3
5
)(7+3
5
)]
=[(7+3
5
)2]/[72–(3
5
)2]
=[72+(3
5
)2+2.7.3
5
]/[49–9.5]
=[49+9.5+42
5
]/[49–45]
=[49+45+42
5
]/[4]
=[94+42
5
]/4
=2[47+21
5
]/4
=[47+21

Answer:
first of all multiply and divide it by neumirator
=>{(2√7+3√2)/(2√7-3√2)}{(2√7+3√2)/(2√7+3√2)}
=>{(2√7+3√2)^2}/{(2√7)^2 - (3√2)^2}
=>{(2√7+3√2)^2}/{(4*7)-(9*2)}
=>{(2√7+3√2)^2}/10
=>{(4*7)+(9*2)+(2*(2√7)*(3√2)}/10
=>{28+18+6√14}/10
=>(23+3√14)/5
