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.

How will you prove that 1^n=1 without proving a^0=1

- 5 years, 3 months ago

${ a }^{ 0 }\quad =\quad { a }^{ b-b }\\ { a }^{ b-b }\quad =\quad \frac { { a }^{ b } }{ { a }^{ b } } \quad =\quad \boxed { 1 }$

Your explanation for a^0 is correct,but you have to prove this in your note.

Rajdeep, this proof is created by me, so please mention it.

- 5 years, 3 months ago

Of course, we're making the assumption that $0^{0}$ is 1, correct?

- 5 years, 3 months ago

No we are not... we can consider a is not equal to 0... instead of "a" we could have used any constant

- 5 years, 3 months ago

Alright, just making sure...
