Question

[(361)^3 -(139)^ 3]÷
[(361)^2- (361X139) +(139)^2​]

Answer 1

Answer:

Either 361-139 or 361+139

Step-by-step explanation:

Your question might be wrong, either the question is [361^3 - 139^3]÷[361^2 + 361x139 +139^2] or the question must be [361^3 + 139^3]÷[361^2 - 361x139 + 139^2].

Note: (a^3 - b^3) = (a^2 + ab + b^2)(a - b)

(a^3 + b^3) = (a^2 - ab + b^2)(a + b)
