qAnswersR[90430] = [];

    qAnswersR[90430].push([math]k: frac{(x+20)^{2}}{256}+frac{(y-15)^{2}}{81}=1[/math]);

And I need to get the value into variable, but when I console.log out the array like this:

console.log(qAnswersR[90430]);

I get: [math]k: rac{(x+20)^{2}}{256}+rac{(y-15)^{2}}{81}=1[/math],[math]k: 81(x+20)^{2}+256(y-15)^{2}=20736[/math]

But the escape tag disappears, but I need it there, what should I do?
