Instructions and Help about Who Form 8815 Index

Okay, today I'm going to teach about some basic laws of indices or exponents. Okay, all right, for this section on indices, there are a few very important laws. The first law is called the power of a power law. It states that when you have a power of a number raised to another power, you multiply the exponents, so a raised to the power of m raised to the power of n is equal to a raised to the power of m multiplied by n. For example, (2^7)^e would be equal to 2^(7e), which can be simplified to 2^(15). Another important law is the division law. It states that when you have a power divided by another power, you subtract the exponents. So a raised to the power of m divided by a raised to the power of n is equal to a raised to the power of m minus n. For example, 2^8 divided by 2^3 would be equal to 2^(8-3), which simplifies to 2^5. The same rules apply to other laws of indices as well. For example, with fractional exponents, the top number represents the power, and the bottom number represents the root. So M^(3/2) can also be written as the square root of M cubed. For example, 7^(2/3) can be written as the cube root of 7 squared. Similarly, when you see expressions like square root(2x+1), you can also write it as (2x+1)^(1/2). Let's consider another example: cube root(4x-7) can be written as (4x-7)^(1/3). There might be instances where you encounter more complex expressions, such as square root(4x-7) squared. In this case, you would square the entire expression, resulting in (4x-7)^(2/2). To simplify the expression further, note that 2/2 is equal to 1. So, the simplified form is (4x-7)^(1). Now let's address what happens when you have negative exponents. When you...
