Exponent Properties

When working with exponents that have the same base, you can use several key properties to simplify expressions. For multiplication, you add the exponents when multiplying terms with the same base $e.g., a^5 · a^3 = a^8$ . This extends to algebraic expressions like $2g^5h^7$ $11g^2h$ = 22g^7h^8.

Division works similarly, but you subtract the exponents (top minus bottom). For example, m^10 ÷ m^3 = m^7, and fractions like 18w^5z^7 ÷ $-9wz^6$ simplify to -2w^4z. When dealing with powers of expressions, use the power rule by multiplying the exponents: $x^3y^5$ ^7 = x^21y^35.

Remember that anything raised to the power of zero equals 1 $e.g., 3^0 = 1$ , and negative exponents move to the opposite side of the fraction line while becoming positive $x^-4 = 1/x^4$ . These rules can be combined to tackle complex expressions like $-3a^4b^7$ ^2 $6a^5b$ ÷ $-2a^7b^2$ = 27a^6b^13.

Pro Tip: When simplifying expressions with multiple exponent rules, always apply the power rule first, then handle multiplication and division. This order prevents common mistakes!

With rational exponents, the numerator represents the power and the denominator represents the root. For example, 81^(3/4) means (∜81)^3, and expressions like (√25)^-3 = 25^(-3/2) = 1/125.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
