How to simplify square roots? Just like simplifying other mathematical expressions, we can simplify square roots in radical form by combining “like terms” or “like radicals” through addition orsubtraction. One essential key when combining radicals by addition or subtraction is to look at the ra...
This lesson will teach you how to simplify and evaluate expressions that contain radicals within radicals. You will see several examples worked out and explained. There you are looking at a math problem that has a root within a root. What are you supposed to do with that? Don't worry! On...
When raising a power to a power, you multiply the exponents, but the bases have to be the same. Because raising a power to a power means that you multiply exponents (as long as the bases are the same), you can simplify the following expressions: Leave the exponent as 9/4. Don’t ...

A historical reason:Before we hadcalculators that could compute radicals, we had to to calculate the value of radicals by hand, and it's much easier to do that when the radical is in the numerator. Share Watch on Simplify Rational Expressions - Grade 9 ...
Radicals are also known as roots, which are the reverse of exponents. With exponents, you raise a number to a certain power. With roots or radicals, you break down the number. Radical expressions can contain numbers and/or variables. To simplify a radical expression, you must first factor ...
The square root of a number is really easy to find. Let's remember first that finding the square root of a number is the opposite of finding the exponent of a number. Moreover, we are only going to deal with positive square roots, a negative square root
