Basic SimplifyingWith Neg. PowersComplex Examples Purplemath Recall thatnegative exponentsindicates that we need to move the base to the other side of the fraction line. For example: x−4=1x−41=1x4x^{-4} = \
In this lesson, expressions such as a⋅bn will routinely appear. Before working with these expressions, it is important to define some vocabulary. In particular, the b is called the base, the n is called the exponent, and the a is called the coefficient. At times, the word "degree" ...
Simplifying Example Distribute. Combine like terms. Evaluating Expressions Evaluate the expression 2x – 3xy +4y when x = 3 and y = -5. To find the numerical value of the expression, simply replace the variables in the expression with the appropriate number. Remember to use correct order of ...
For operations on radical expressions, change the radical to a rational expression, follow the exponent rules, then change the rational expression back to a radical expression. By the end of this lesson you'll be able to simplify expressions with rational exponents. Read Simplifying Algebraic ...

It may be possible to get simpler expressions by putting appropriate assumptions (e.g., real, positive, etc.) on the variables if appropriate. Lu Zhaoon 29 Mar 2021 That is great! I learned a lot from it. Than you. I really appreciate it. : D ...
I was looking for a type that could express this but was unable to. So instead we’re still going to stick with the semi_normal_form type and just transform any such expression into one that is guaranteed to be in normal form. We won’t have the type system ensuring this for us, ...
