In the example, underneath, you will see that x to the power of 0 is always equal to 1. Effective Teaching Explanations, examples and questions combined for an effective learning experience. Step 1 : Apply the Zero-Exponent Rule. So, the solution is 3 to the power of 5. If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents. The a represents the number and n and m represent the powers. The concept of a power is quite simple but just to ensure that you have understood everything in the introduction and you are ready to proceed, look at the examples underneath.

Laws of Exponents.

## Powers and Exponents

Exponents are also called Powers or Indices. 8 to the Power 2. The exponent of a number says how many times to use the number in a. Exponent rules, laws of exponent and examples. What is an exponent.

The base a raised to the power of n is equal to the multiplication of a, n times. power or 5 cubed, 5 ∙ 5 ∙ 5. 26, 2 to the power of six, 2 ∙ 2 ∙ 2 ∙ 2 ∙ 2 ∙ 2 When we multiply two powers we add their exponents. The rule: The rule for the power of a power and the power of a product can be combined into the following rule.

Step 4 : Apply the Product Rule.

Example 1 — Simplify:.

## Powers and the Laws of Indices

Example 3 —Simplify:. To multiply two exponents with the same base, you keep the base and add the powers. Step 2 : Apply the Power Rule.

Powers To ensure that you properly understand this topic, we recommend you to read the indices introduction.
In algebraic form, this rule looks like this. In this case, the product rule does not apply. If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents. If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. This expression can be written in a shorter way using something called exponents. |

Product Law. The quotient law states that when dividing powers with the same base, keep the base and subtract the exponents.

Example 1 In this example, we have 4 to the power of 3 which is equal to 4 x 4 x 4.

There are several other rules that go along with the power rule, such as the product-to-powers rule and the quotient-to-powers rule. In this case, there are no zero powers.
