If its a single fraction term such as 10ab14a2 then use exponent rule and reduce the fraction to 10b14a.
How to simplify complex fractions with variables and exponents. Remember to distribute the negative or subtraction sign between the two fractions. To simplify complicated radical expressions we can use some definitions and rules from simplifying exponents. Recall the Product Raised to a Power Rule from when you studied exponents.
Easy way to find least common denominator. Below is a specific example illustrating the formula for fraction exponents when the numerator is not one. Simplifying nestedcomplex fractions with variables.
You can either apply the numerator first or the denominator. There are two ways to simplify a fraction exponent such frac 2 3. I cant cancel off say the a s because that a 4 isnt really on top.
Before I can cancel anything off I need to simplify that top parentheses because it has a negative exponent on it. The exponent rules tell me to subtract the exponents. However the cancellation of variables or terms which contain variables in the denominator should be handled carefully.
This rule states that the product of two or more non-zero numbers raised to a power is equal to the product of each number raised to the same power. Simplify the rational expression in the numerator of the original problem by subtracting the fractions. Use the power property of exponents to simplify expressions Use the product to a power property of exponents to simplify expressions You have seen that when you combine like terms by adding and subtracting you need to have the same base with the same exponent.
