In this video, I'm going to show you how to work with fractional powers. As an example, let's take 16 to the power of 1/2. The power of 1/2 is the same as the square root, so 16 to the power of 1/2 is the square root of 16, which is 4. In higher-level math, it's important to remember that it could also be -4 because -4 multiplied by -4 will also give you 16. Using this plus or minus symbol, we can write it as plus or minus 4. So, if you had 25 to the power of 1/2, it would be the square root of 25, which is 5, but it could also be -5. Similarly, if we have the power of 1/3, it means the cube root. For example, if we want to find the cube root of 8, we need to find a number that, when multiplied by itself three times, equals 8. In this case, that number is 2, as 2 multiplied by 2 multiplied by 2 equals 8. So, the cube root of 8 is 2. If we look at another example, 27 to the power of 1/3 means finding the cube root of 27. In this case, the number is 3, as 3 multiplied by 3 multiplied by 3 equals 27. When dealing with cube roots, if you familiarize yourself with the cubes of numbers like 2, 3, 4, and 5, it will make calculations easier. Sometimes, we may come across fractional powers with a top number that is not 1, such as 125 to the power of 2/3. In such cases, we first convert it to a power of 1. So, 125 to the power of 2/3 becomes the cube root of 125, which is 5. This value then needs to be...
