9^x . 3^x=15×3 9^x.3^x=45 9^x=45/3 9^x=15 x=9/15 x=3/5

John 🏴󠁧󠁢󠁷󠁬󠁳󠁿 :

x=ln(45)/(3×ln(3))≈1,1549911736 ((3²)ˣ•3ˣ)÷3=15 (3²)ˣ•3ˣ=3³ˣ=45 3x ln(3)=ln(45) x=ln(45)/(3×ln(3))≈1,1549911736

dzr :

27^x = 45 3^(3x) = 45 3x = log(45)/log(3) 3x = 2 log(3)/log(3) + log(5)/log(3) 3x = 2+³log(5) x = ⅓(2+³log(5))

mohamedberkani777 :

3^(3x–2)=5→ 3x–2=log3(5)→x=(log3(5)+2)/3

jimteng1 :

(9^x*3^x)/3=15 (3^2x*3^x)/3=15 3^3x=3*15 3^3x=45 3x*ln3=ln45 x=ln45/(3*ln3)=1.155

silvert0307 :

х = (1/3)•(2 + log5/log3) x ~ 1.1549911... 🫠

ратмир :

9**х × 3**х/3=3**2х × 3**х/3=3**3х/3=15=> 3**3х=45=>х≈1,15499

Екатерина :

х=lg45/lg27

АндреБас2004 :

(9^x * 3^x) / 3 = 15 9^x * 3^x = 15 * 3 9^x * 3^x = 45 (9 * 3)^x = 45 27^x = 45 27^x = 27^(log(27, 45) => x = log(27, 45) ✅

45..

Pete H61 :

I think some folks here are conflating exponentiation and multiplication. If x=3/5, 9^x-3^x is irrational, never mind an integer

xcvieef :

3/5

Yuninda Surya :

9x.3x/3=15 27x²/3=15 9x²=15 x²=15/9 x²=5/3 atau 1.29

Aa Pipik.com :

3^3x - 2 = 5 (3x - 2) log 3 = log 5 3x log 3 - 2 log 3 = log 5 3x log 3 = log 5 + 2 log 3 3x = log 5/log 3 + 2 log 3/log 3 3x = log 5/log 3 + 2 x = log 5/3 log 3 + 2/3

x=(ln(5)/ln(3)+2)/3

45/3. must be 45/3^x
