How do you solve exponential inequalities?

Back

To solve exponential inequalities, you can take the logarithm of both sides, use properties of exponents, or rewrite the inequality in a comparable form. Always consider the base of the exponent when determining the direction of the inequality.

What is the significance of the base in exponential inequalities?

Back

The base determines the direction of the inequality when comparing exponential expressions. A base greater than 1 maintains the inequality direction, while a base between 0 and 1 reverses it.
