31 Μαρ 2023 · Learn about the concept of exponents and how to evaluate powers, how to multiply & divide powers, and to raise powers to powers. Watch now!
In this video, we will learn how to apply the laws of exponents to multiply and divide powers and to calculate a power raised to a power over the real numbers. We should already be familiar with what powers are and the key laws of exponents. But we we’ll recap them briefly here.
Exponents, Power Rule, Quotient Rule, Zero Rule, Negative Rule, How to use the exponent rules, How to simplify expressions with rules of exponents, How to evaluate expressions with negative exponents, Grade 7 math, with video lessons, examples and step-by-step solutions.
The "Laws of Exponents" (also called "Rules of Exponents") come from three ideas: The exponent says how many times to use the number in a multiplication. If you understand those, then you understand exponents! And all the laws below are based on those ideas. Here are the Laws (explanations follow):
Exponents, Roots (such as square roots, cube roots etc) and Logarithms are all related! Let's start with the simple example of 3 × 3 = 9:
When it comes to the key points here, simplifying expressions allows us to write an expression in the most compact and efficient manner without changing the value of the expression. And when those expressions have exponents, we can use these basic rules to help us simplify.
