Doubt-3

Solve in real numbers the equation below.

(1019x)1/2(2019+x)1/3=16 (1019-x)^{1/2} - (2019 + x)^{1/3} = 16

Can someone give a method to solve this question or a similar question. Thanks!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Comments

Let (1019-x)^(1/2)=P and second term be Q. Then you have, P-Q=16. P^2+Q^3=3038 =>Q^3+(Q+16)^2=3038. So, you have a cubic equation in Q, which has only one real root, 13. Hence x=178.
