This is insane...I'm impressed...and would you consider reducing the volume of the music?

The trick involves recognizing that 30 is the sum of a number and its cube. However, if you can do that, you can just solve the original equation by inspection once you have made the substitution y = 2^x. I suppose an advantage of this factoring approach is finding other real roots of the cubic, if they exist.

i used logarithms immediately and used a calculator to get the exact values

(2^x)^3+2^x=3^3+3 f(z)=z^3+z is a bijective function R-->R so 2^x=3, x=log3/log2

Just try learning algorithms and data structures without mathematics. The suffering would be immensely unbearable. :(

Не особо нужно, но для работы с 3D движком на каком нибудь OpenGL - да. А так основы мат 5 класса достаточно

I saw this equation and knew it didn't work with whole numbers immediately. 8 is the third exponent of 2. We're adding exponents of 2, none of which add to 30. Adding two positive exponents of 2 don't result in a number where if you divide it by 2, it results in an odd number.

Thank you for sharing your observation! You're absolutely correct that this equation doesn't yield a whole number solution. It's interesting to note the relationship between exponents of 2 and the lack of a solution for the given condition. Your observation adds depth to the problem-solving process. Thanks again for engaging with the content.

Just ask ChatGPT, both 8 and 2 are positive, the sum of positive can not be 0. So no solution
