Question: algaebra exponent questions a^b

By the definition of exponents:- a^b is the base multiplied by itself the number of times indicated by the power.

You have a question: 2^8^2 and your "correct" solution was 2^64 and the obvious solution of 2^16 was marked as wrong.

In site has a wrong answer published:-

2^8^2 is published as 2^64 which is wrong answer. It may seem logical but it still wrong. I believe that your site should validate all its answers prior to publishing.

The correct answer is 2^16. The trivial problem of 2^3^2 2^3^2 = (2^3)^2 = 8^2 = 64 Do we: add, multiply or eval as powers a complex power: multiple all else is wrong is: 2^3^2 = 2^6 or 2^9

2^3^2 = (2^3) x (2^3) = (2x2x2) x(2x2x2) = (2x2x2 x 2x2x2) = 2^6

pls remember 10x10x10 = 10^3

The additional rule of:- a^(bxc) =a^(cxb) = a^b^c = a^c^b

I have been looking at some of your questions and the rigor of some of your solutions is a but dubious on some occassions. On some occassions the question statement needs to be complete and without ambiguity.

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.

No, this is a common misconception. See this article: How are exponent towers evaluated?
