## 17Calculus Precalculus - Exponent Rules

##### 17Calculus

In calculus you will be required to understand and be able to use the rules of exponents. Most instructors will not go over these rules before jumping into calculus. So make sure you know them well.

List of Rules

Let's start by going through these exponent rules.

 1. The Product Rule $$x^n \cdot x^m = x^{n+m}$$ 2. The Quotient Rule $$\displaystyle{ \frac{x^n}{x^m} = x^{n-m} }$$ 3. The Power Rule $$(x^n)^m = x^{n \cdot m}$$ 4. Power of Zero $$x^0 = 1$$ 5. Negative Exponents $$\displaystyle{ x^{-n} = \frac{1}{x^n} }$$ 6. Fractional Exponents $$x^{1/n} = \sqrt[n]{x}$$ 7. Distribute An Exponent Over a Product $$(x \cdot y)^n = x^n y^n$$ 8. Distribute An Exponent Over a Quotient $$\displaystyle{ \left( \frac{x}{y} \right)^n = \frac{x^n}{y^n} }$$

In this video clip, the instructor explains these rules very well and includes some examples.

Okay, let's practice simplifying on these problems.

Practice Simplifying

$$5-2(x^{-3}x^4)^0$$

Problem Statement

Simplify $$5-2(x^{-3}x^4)^0$$ using the exponent rules, giving your answer in exact form.

$$3$$

Problem Statement

Simplify $$5-2(x^{-3}x^4)^0$$ using the exponent rules, giving your answer in exact form.

Solution

Comment: Although in general, his answer is correct, he is making an assumption that $$x \neq 0$$. He doesn't need to state this since it is implied by the term $$x^{-3}$$. If $$x = 0$$ is part of the domain, this term would be $$0^{-3} = 1/0^3 = 1/0$$. Remember in algebra, we never want the denominator to be zero. So, in this case the domain does not include zero. So he doesn't have to worry about the case $$0^0$$ for this problem.
