Answer: 545

Solved using the script below:


console.log("********************************");
function func(x){
return Math.pow(x,4)+64;
}
var numproduct=1;
for(var i=8; i<=64; i+=8){
var temp = func(i);
console.log(i+" "+temp);
numproduct *= temp;
}

var denproduct=1;
for(var i=4; i<=60; i+=8){
var temp = func(i);
console.log(i+" "+temp);
denproduct *= temp;
}

console.log(numproduct/denproduct);
