Maaf yang tadi salah,yang bener ini 🙏🏻mohon bantuannya kak😭

3) √5^x+2 = 25^x-2 » √5^x+2 = (5²)^x-2 » 5^( (x+2)/2 ) = 5^( 2(x-2) ) » x+2 / 2 = 2(x-2) » x+2 / 2 = 2x - 4 » (x + 2 / 2) 2 = (2x - 4) 2 → kalikan kedua ruas » x + 2 = 4x - 8 » 2 + 8 = 4x - x » 10 = 3x » 10/3 = x <=> x = 10/3 4) ²log 3 + ²log 2 - ²log 6 - ²log 8 = ²log 3 + 1 - ²log 6 - ²log 2³ = ²log 3 + 1 - ²log 6 - 3.²log 2 = ²log 3 + 1 - ²log 6 - 3 = 1 - 3 + ²log 3 - ²log 6 = -2 + ²log (3/6) = -2 + ²log 1/2 = -2 + ²log 2^-1 = -2 + (-1) . ²log 2 = -2 + (-1) . 1 = -2 + (-1) = -3 5) ¹²log 54 = ²log 54 / ²log 12 = ²log 2.3³ / ²log 2².3 = ²log 2 + ²log 3³ / ²log 2² + ²log 3 = ²log 2 + 3. ²log 3 / 2. ²log 2 + ²log 3 = 1 + 3a / 2.1 + a = 1 + 3a / 2 + a = 3a + 1 / a + 2 Semoga membantu!
