  1. Exponentialgleichungen SABOVIC Iman

  2. log kann mit Tasten in den Taschenrechner eingegeben werden. Dividiert man 0 durch einen Nenner, ist das Ergebnis automatisch 0. 5³x = 7²x /log log = log 3x log5 = 2x log7 / -2x log7 3x log 5 - 2x log7 = 0 x (3 log 5 - 2 log7) = 0 x = 0 (3 log5 - 2 log7) x = 0

  3. Bei einer Exponential- gleichungmuss man beide Seiten logarithmieren und dann x auf eine Seite bringen. Wichtig sind dabei die Regeln für das Rechnen mit Logarithmen! 25x+1 = 34x /log log 25x+1 = log 34x (5x + 1) log 2 = 4x log 3 5x log2 + 1 log2 = 4x log 3 /-4x log3 - log2 5xlog2 – 4x log3 = -log2 x (5log2 – 4 log3) = - log2 /: (5log2 – 4log3) x= - log 2 (5log2 – 4log3) x = 0,746
