Prove that the equation $a^4+b^4+c^4-2a^2b^2-2b^2c^2-2a^2c^2=24$ has no solution in integers $a,\,b,\,c$.

Having no solution in integers means that there are no whole number values that can be substituted into the equation to make it true.
To prove that an equation has no solution in integers, you can use a proof by contradiction. Assume that there is a solution in integers and then show that it leads to a contradiction, proving that the original assumption was false.
Yes, an equation can have no solution in integers but still have solutions in other number sets such as rational or real numbers. For example, the equation x^2 = -1 has no solution in integers but has solutions in the set of complex numbers.
Yes, equations involving irrational numbers or ones that result in a non-integer answer are more likely to have no solution in integers. For example, the equation x^2 = 2 has no solution in integers because the square root of 2 is an irrational number.
Proving that an equation has no solution in integers can help eliminate unnecessary steps in problem-solving and prevent errors in calculations. It also allows us to understand the limitations of certain equations and number sets.
