## What is rational exponent equation?

Definition: Rational Exponents. A rational exponent indicates a power in the numerator and a root in the denominator. There are multiple ways of writing an expression, a variable, or a number with a rational exponent: amn=(a1n)m=(am)1n=n√am=(n√a)m. Example 1.5.

**What is an example of a rational exponent?**

Definition. A rational exponent is written as x a b , x^{ \frac{a}{b}}, xba, with base x x x and exponent a b \frac{a}{b} ba. This expression is equivalent to the b th b^{\text{th}} bth-root of x x x raised to the a th a^{\text{th}} ath-power, or x a b \sqrt[b]{x^a} bxa .

### How do you solve a rational exponent equation?

When solving a rational exponent equation, you first isolate the variable. Then, to eliminate the exponent, you will need to raise everything to the reciprocal power. Let’s determine if x = 9 is a solution to \begin{align*}2x^{\frac{3}{2}}-19=35\end{align*}. Substitute in x and see if the equation holds.

**What do fraction exponents mean?**

A fractional exponent is an alternate notation for expressing powers and roots together. For example, the following are equivalent. We write the power in numerator and the index of the root in the denominator. If there is no power being applied, write “1” in the numerator as a placeholder.

## What is 5 with an exponent of 1?

5

Answer: 5 to the power of 1 is 5. Let’s solve this question by using rules of exponents and power by following steps.

**What are the steps in solving rational equations?**

Solve equations with rational expressions. Step 1. Note any value of the variable that would make any denominator zero. Step 2. Find the least common denominator of all denominators in the equation. Step 3. Clear the fractions by multiplying both sides of the equation by the LCD. Step 4. Solve the resulting equation. Step 5. Check:

### How do you solve exponent equations?

Keep the exponential expression by itself on one side of the equation.

**How to evaluate rational exponents?**

EVALUATE INTEGERS RAISED TO RATIONAL EXPONENTS. The following steps will be useful to evaluate integers with rational exponents. Step 1 : Write the base in exponential notation. Step 2 : Multiply the two exponents simplify.
