$\bf\Huge\red{\mid{\overline{\underline{ ANSWER }}}\mid }$

➡️Consider LHS 3! + 4!

➡️Computing left hand side, we get

➡️3! + 4! = (3 × 2 × 1) + (4 × 3 × 2 × 1)

➡️ 6 + 24

➡️ 30

➡️Again consider RHS and computing we get

➡️7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040

➡️Therefore LHS ≠ RHS

➡️Therefore 3! + 4! ≠ 7!
