Question

formalate into a mathematical problem to find a number such that when its cube root is added to the result is 6​

Answer 1

Answer:

Let the number be x.

Given that

Cubing on both sides

x = (6 – x)3

⇒ x = 216 – 3 (6)2 (x) + 3(6) (x)2 – x3

⇒ x = 216 – 108x + 18x2 – x3

⇒ x3 – 18x2 + 109x – 216 = 0
