Exponential Equations (AQA A-Level Mathematics): Flashcards

Take logs of both sides

$b\log(a)$

Yes, same result

Raise $a$ to both sides: $x = a^k$

$x$

$x$

No, can't distribute power over addition

Single term on each side

Logs of negatives don't exist

$x = \frac{\log(2.8)}{\log(5)} \approx 0.640$
