no it is not an irrational no. as it can not be written in the form of p/q

hope it helps....

Answer:

First of all we assume that give no. is rational no. the we will proves ourselves wrong

so assuming given no is a/b

 \sqrt{2}  +  \sqrt{3}  =  \frac{a}{b}  \\ where \: a \: and \: b \: are \: rational \: no. \\ squaring \: both \: side \:  \\ ( \sqrt{2}  +  \sqrt{3} ) ^{2}  =  \frac{a}{b}  \\ 2 + 3 + 2 \sqrt{2}  \sqrt{3}  =  \frac{a}{b}  \\ 5 + 2 \sqrt{6}  =  \frac{a}{b}  \\ 2 \sqrt{6}  =  \frac{a}{b}  - 5 \\ 2 \sqrt{6}  =  \frac{a - 5b}{b}  \\  \sqrt{6}  =  \frac{a - 5b}{2b}  \\ here \: on \: the \: right \: hand \: side \: is \: rational \: no. \\  and \: left \: side \: is \: irrational \: no. \:  \\ so \: our \: assumption \: was \: wrong \\  \sqrt{2}  +  \sqrt{3} \:  cannot \: be \: equal \: to \:  \frac{a}{b}  \\ so \sqrt{2}  +  \sqrt{3} \:  is \: irrational


Hitha05: thank you a lot
