Laws of Exponents. Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the second power", "8 to the power 2" or simply "8 squared". Try it yourself:

How to apply the laws of exponents explained with a video tutorial and practice problems explained step by step
Exponent rules are those laws that are used for simplifying expressions with exponents. Learn about exponent rules, the zero rule of exponent, the negative rule of exponent, the product rule of exponent, and the quotient rule of exponent with the solved examples, and practice questions.
In simple terms, just treat the numerator and denominator separately when distributing by multiplication the inner and outer exponents for each factor. Get started learning about the Rules or Laws of Exponents with this comprehensive introduction. Use the rules of exponents to simplify algebraic expressions.
Here you will learn about the laws of exponents, including what the laws of exponents are and how you can use them. You’ll also learn how to write an expression using exponential notation and how to find the cube root of an integer.
From this definition, we can deduce some basic rules that exponentiation must follow as well as some hand special cases that follow from the rules. In the process, we'll define exponentials $x^a$ for exponents $a$ that aren't positive integers.
Exponent Formula: When a number 'a' is raised to the power 'n', it means 'a' is multiplied by itself 'n' times: a^n = a × a × ... (up to n times) Here, 'a' is our base while 'n' stands as the exponent. Illustrative Examples: 3^1 = 3. 3^2 = 3 × 3 = 9. 3^3 = 3 × 3 × 3 = 27. 3^4 = 3 × 3 × 3 × 3 = 81. 3^5 = 3 × 3 × 3 × 3 × 3 = 243.
