solving exponential equations
Subject:
Algebra [1]
to solve exponential equations without logarithms, you need to have equations with comparable exponential expressions on either side of the "equals" sign, so you can compare the powers and solve. In other words, you have to have "(some base) to (some power) equals (the same base) to (some other power)", where you set the two powers equal to each other, and solve the resulting equation. For example:
Solve 5x = 53.
Since the bases ("5" in each case) are the same, then the only way the two expressions could be equal is for the powers also to be the same. That is:
x = 3
