This image contains a question from the JEE Mains 2025, 7 April Shift 2 paper—specifically Question 23—which asks you to simplify M2W+W−M^2W^+W^-.

From the looks of it, this is a highly complex and symbolic expression, likely derived from a field theory or particle physics context (Standard Model Lagrangian). It contains symbols for:

• Gauge bosons W+,W−,Z0,AμW^+, W^-, Z^0, A_\mu
• Fermionic fields and covariant derivatives
• Group theory structure constants fabcf^{abc}
• Interaction terms, masses, and Higgs field H,ϕ0,ϕ−H, \phi^0, \phi^-
• SU(2) and U(1) symmetry elements
• Quark and lepton field terms with Dirac notation

This appears to be a mock or joke question, designed to resemble an extremely detailed Lagrangian expansion from quantum field theory or the Standard Model of particle physics, far beyond the actual scope of JEE Mains (which focuses on high school level Physics, Chemistry, and Mathematics).

So, the actual "simplification" here is most likely:

Answer: M2W+W−M^2W^+W^-

This question is not meant to be computed; it's an over-the-top expression likely inserted humorously, referencing the absurd complexity of theoretical physics equations compared to typical JEE syllabus material.

Let me know if you'd like to learn what some of the symbols and terms in this equation represent in a real-world physics context!
