EXPONENTS AND RADICALS. Rational exponents (also called fractional exponents) are expressions with exponents that are rational numbers (as opposed to integers ). (n=given power value) And the important note is `sqrt(y) xx sqrt(y) = y` For example: How to solve the given radical exponent value `sqrt (5) ^ (2)` Solution: Given:` sqrt (5) ^ (2)` = `sqrt (5) * sqrt (5)` =` 5.` So, answer is 5. Evaluate numerical expressions with rational exponents, and convert between equivalent forms of exponential and radical expressions. 2⁹ = 8ⁿ, what is Trouble with Radicals, But Not with Rational Exponents? Finally we add another kind of equation to our growing list, the radical equation. If no index is given, then the index is assumed to be 2 (2nd root, aka the square root). If you combine a radical with an integer exponent then you can express the same concept as a rational exponent. The properties of exponents apply to rational exponents. When using this method to simplify roots, we need to remember that raising a power to a power multiplies the exponents. When we use rational exponents, we can apply the properties of exponents to simplify expressions. Multiplying and dividing exponents. x² * x⁵ = ? Are you looking for an algebra trivia quiz on Exponents and Radicals? Glossary.
