@Math_World_ π

I picked a number between 1 and 10. Guess it?

@timricchuiti Yesss 👏🏻👏🏻

@vannref24 @mathhub_vn @karadagmetin2 Thanks

@Math_World_ @mathhub_vn @karadagmetin2 a more efficient way

@Math_World_ A=1 + 2 + 2² + 2³ + ···+ 2²⁴ =1・[( 2 ²⁵ - 1 )/( 2 - 1)] = 2 ²⁵ - 1 ― ① Substitute ① for ②. √ log( A + 1 )/ log 2 ― ② =√ log ( 2 ²⁵ - 1 + 1 )/ log 2 =√( 25 log 2 )/ ( log 2 ) =√ 25 =５

@MathhWizard 👏🏻👏🏻

@Math_World_ A + 1 = 33.554.432 = 2²⁵log₂(A + 1) = log₂(2²⁵) = 25 √((log(A+1)) / log(2)) = √(log₂(A+1)) = 5

@Math_World_ Ｕ´･ω･`Ｕ x+y=15/2 ⋯ ① x･y=9 ⋯ ② (→ x≠0, y≠0) ②/x → y=9/x ⋯ ③ → ① x+(9/x)=15/2 → 2x^2-15x+18=0 (2x-3)(x-6)=0 ∴ x=3/2, 6 → ③ ∴(x, y)=(3/2, 6), (6, 3/2)

@Moossell 👍🏻

@Math_World_ 6, 1.5

@Math_World_ x + y = 15/2 xy = 9 t² – (15/2)t + 9 = 0 2t² – 15t + 18 = 0 Δ = 225 – 144 = 81 √Δ = 9 t = (15 ± 9)/(2·2) = (15 ± 9)/4 t₁ = 24/4 = 6 t₂ = 6/4 = 3/2 x = 6, y = 3/2 ou x = 3/2, y = 6
