Question

If 1 2 ... n=k then 1^3 2^3 ... n^3 is equal to

Answer 1

Answer:

If 1 2 ... n=k then 1^3 2^3 ... n^3 is equal to k^3 .

Step-by-step explanation:

[ as we know that k^n means k is raised to the power n.]

If 1 2 ... n = k

then,

1^3 2^3 ... n^3

= (1 2 ... n)^3   [ since a^n ⋅ b^n. c^n . ... = (a ⋅ b. c)^n

= k^3     ( since 1 2 ... n = k)

Therefore 1^3 2^3 ... n^3 will be k^3
