Answer 2

Given :

2*3=√13

3*4=5

To find :  5*12 = ?

Solution :

$2*3=\sqrt{13}\\\sqrt{2^2+3^2}=\sqrt{4+9}=\sqrt{13}$

Similarly,

$3*4=5\\\\\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$

So, we get that :

$5*12\\\\=\sqrt{5^2+12^2}\\\\=\sqrt{25+144}\\\\=\sqrt{169}\\\\=13$

Hence, the value of 5*12= 13.
