We’ll start with equations that involve exponential functions. The main property that we’ll need for these equations is, Example 1 Solve 7 +15e1−3z = 10 7 + 15 e 1 − 3 z = 10 . Example 2 Solve 10t2−t = 100 10 t 2 − t = 100 .
WebWe can solve equations in which a variable is raised to a rational exponent by raising both sides of the equation to the reciprocal of the exponent. The reason we raise the equation to the reciprocal of the exponent is because we want to eliminate the exponent on the variable term, and a number multiplied by its reciprocal equals 1. WebTo 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. ... and solve the resulting equation. For example: Solve 5 x = 5 3; Since the bases ("5" in each case) are the same, then the only way the two ...
