Beginners AAgebra 4: Index Notation

Index Notation is a simple area of maths and is not just part of algebra. If you have multiple of the same numbers multiplying by each other and the question asks you to put it in index form you don't solve it but what you do is you put the number (Base Number) and the small number to the top right (Power Number*). Here is an example below

2 x 2 x 2 = 232^{3}

if you see multiple of the same numbers and multiple of another number also like below and you are required to put them in index form DO NOT MIX THEM as this is incorrect.

3 x 3 x 3 x 5 x 5 x 5 x 5 x 5 = 3 x 3 x 3 = 333^{3} ; 5 x 5 x 5 x 5 x 5 = 555^{5}

therefore: 3 x 3 x 3 x 5 x 5 x 5 x 5 x 5 = 333^{3} x 555^{5}

Now we understand the basics of it lets use it in algebra. When beginners hear algebra get involved they think it is very complicated but it is not if you use the same thing as you did before.

a x a x a x b x b x b x b x b = a3a^{3} x b5b^{5}

More Coming Soon! This will be a question soon but until i have put all the info i am saving it as a draft as a conversation. ETP-5 days

(Note this should not be taken as an official guide and it is recommended you still study further.)

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
