j^(3)+3j^(2)k+3jk^(2)+k^(3) Which of the following is equivalent to the given expression? Choose 1 answer: (A) j^(3)+3(jk)^(2)+k^(3) (B) j^(3)+6(jk)^(2)+k^(3) (c) j^(3)+3jk(j+k)+k^(3) (D) j^(3)+6jk(j+k)+k^(3)

Given expression: The given expression is j^(3)+3j^(2)k+3jk^(2)+k^(3). We need to identify which of the provided choices is equivalent to this expression.Recognizing the binomial expansion: Recognize that the given expression is the expansion of (j+k)^3 based on the binomial theorem, which states that (a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3.Comparing the given expression to the binomial expansion: We can compare the given expression to the binomial expansion: j^(3)+3j^(2)k+3jk^(2)+k^(3) matches the form a^3 + 3a^2b + 3ab^2 + b^3 with a=j and b=k.Comparing the given expression to the answer choices: Now, let's compare the given expression to the answer choices: (A) j^(3)+3(jk)^(2)+k^(3) simplifies to j^(3)+3j^2k^2+k^(3), which is not the same as the given expression.Identifying the correct answer: (B) j^(3)+6(jk)^(2)+k^(3) simplifies to j^(3)+6j^2k^2+k^(3), which is also not the same as the given expression.(C) j^(3)+3jk(j+k)+k^(3) simplifies to j^(3)+3j^2k+3jk^2+k^(3), which matches the given expression exactly.(D) j^(3)+6jk(j+k)+k^(3) simplifies to j^(3)+6j^2k+6jk^2+k^(3), which does not match the given expression.Therefore, the correct answer is (C) j^(3)+3jk(j+k)+k^(3), which is equivalent to the given expression.
