 2^x 3^y = z^2 1 where x, y, and z are nonnegative integers We can see that 1 is a congruence modulo 8 3^y = z^2 (mod 8) 2 When z=1 and and y=2 we have 3^2 = 1 (mod 8) 3 and by Fermat's theorem So this means that y must be even As y is even, we can write y = 2k for some integer k So we have 3^2k 2^x = z^2 z^2 3^2k = 2^xConsider x 3 y 3 z 3 − 3 x y z as a polynomial over variable x Find one factor of the form x^ {k}m, where x^ {k} divides the monomial with the highest power x^ {3} and m divides the constant factor y^ {3}z^ {3} One such factor is xyz Factor the polynomial by dividing it by this factorA classic way to prove inequalities is using AMGM inequality But my approach is different Here's my proof According to an algebraic identity, mathx^3 y^3 z

Calc 3 Level curves Close 1 Posted by 6 years ago Archived Calc 3 Level curves Let k(x,y)= 4x 2 8x 5y 2 3 Sketch the level curves for c= 1, 15, and I got a hyperbola from this, but now I'm in doubt because one of the values of c make it undefined Is this possible?When drawing in three dimensions is inconvenient, a contour map is a useful alternative for representing functions with a twodimensional input and a onedimensional outputSo again, we want to try to do visualize the level surfaces dysfunction And so you could pick anything you wanted Let's say we picked K equaling zero In other words, on the set of all points X y Z, for which the output of the function is zero So zero is equal to Z squared minus X squared, minus y squared
