Question

If 2³ +4³+6³ + .......+(2n) ³= kn² (n+1)² , then k =​

Answer 1

Answer: the value of k is 2

Step-by-step explanation:

Given that,

2³+4³+6³+.......+(2n)³=kn²(n+1)²

Common 2³ from the above equation,

2³(1³+2³+3³+........+n³)=kn²(n+1)²

2³(n²(n+1)²)/4=kn²(n+1)²

K=2³/4

K=8/4=2

So the value of k is 2

Hope it helps you frnd........
