# How to Calculate 3^2048: Step-by-Step Guide

• tsuwal
In summary, to prove the given equation, start by using the given answer of 3^2048. From there, use the formula a^2 - b^2 = (a-b)(a+b) with a = 2^2048 and b = 3^2048. Repeat this process with a = 2^1024 and b = 3^1024, and continue until the last pair on the left. This will result in (2-3)(2+3), giving a minus sign in the equation.

the answer is 3^2048. How do I get there?

Since you are given the answer, use that information!

You have to prove that
##(2+3)(2^2+3^2)\cdots(2^{2048} + 3^{2048}) + 2^{4096} - 3^{4096} = 0##
Now, think what you can do with ##2^{4096} - 3^{4096}## ...

i don't know, what can i do :S?

and the answer is not given, it's multiple choice

a2 - b2 = (a-b)(a+b)

next repeat with a = 21024 and b = 31024
etc.
At the end you will have (2-3)(2+3). Just be careful with the sign.

No, its a minus sign:
##(2+3)(2^2+3^2)\cdots(2^{2048} + 3^{2048}) + 2^{4096} - 3^{4096} = 0##
AlephZero was referring to the last pair on the left.

now i get it. thanks!
