javascript如何求次方和

varn1=Math.pow(1,2);
varn2=Math.pow(2,2);
varn3=Math.pow(3,2);
varn4=Math.pow(4,2);
varn5=Math.pow(5,2);
console.log(n1);
console.log(n2);
console.log(n3);
console.log(n4);
console.log(n5);

varsum=n1+n2+n3+n4+n5;

Math.pow(x,y)

console.log(Math.pow(0,1));
console.log(Math.pow(1,0));
console.log(Math.pow(1,1));
console.log(Math.pow(1,10));
console.log(Math.pow(3,3));
console.log(Math.pow(-3,3));
console.log(Math.pow(2,4));

varn=5;//
console.log(NaN+n);//NaNNaN
console.log(Infinity+n);//InfinityInfinity
console.log(Infinity+Infinity);//InfinityInfinityInfinity
console.log((-Infinity)+(-Infinity));//InfinityInfinity
console.log((-Infinity)+Infinity);//InfinityNaN

console.log(1+1);//
console.log(1+"1");//
console.log(3.0+4.免费云主机、域名3+"");//"7.3"
console.log(3.0+""+4.3);//"34.3"
//3.03
