One term of an expansion for (m+y)^10 is 20160x^4y^6

Question

One term of an expansion for (m+y)¹⁰ is 20160x⁴y⁶.

Use the general term formula, _n^C_k=(x)^n-k(y)^k, to algebraically determine the value of m.

Answer 1

Hi Parth B.,

Please parse your questions for completeness! There is no x term in the (m+y)^10 expression, therefore you have one equation in two variables, no unique solution.

Revise your question, and perhaps someone may help you!

Mercy hint: you might just try (mx+y)^10 ??? You should then be able to pull m^4 out of the 20160, and solve for m.
