Mathematical sbi contest #5
Here you can keep your brain fit by solving math related problems and also earn SBI by doing so.
The problems usually contain a mathematical equation that in my opinion is fun to solve or has an interesting solution.
I will also only choose problems that can be solved without additional tools, so don't grab your calculator, you won't need it.
No upvote, No resteem, No follow required!
I will give 1 SBI to a random person who put a correct solution of the problem in a comment.
You have 48 hours to solve it.
In case there are multiple solutions, you have a higher chance of winning if you get all of them correctly.
Solutions can sometimes also be general like
x = 20, y > -1. If there are multiple solutions submitted, that are part of the same general solution, they will be counted as one solution.
And one more thing: I only want integer solutions!
Today an equation without a variable in the exponent.
You can take a look at the results of the last contest here.
To everyone who already participated in a past contest, come back today and try a new problem(tell me if you don't want to be tagged):
@addax @ajayyy @bwar @heraclio @sidekickmatt @tonimontana @vote-transfer
In case no one gets a result(which I doubt), I will give away the 1 SBI to anyone who comments.
This contest is over! You can find the results here.
