The solution of the equation mod z

WebFor our purposes, a diophantine equation is an equation with integer co-ecients where the solutions are also required to be integers. The simplest examples are the linear ones: given integers a,b,c, find all integers m,n such that am+bn = c. Theorem 8.11. Given integers a,b,c, am+bn = c has a solution with m,n 2 Z if and only if gcd(a,b) c. Proof. WebFor a system of two linear equations and two variables, there can be no solution, exactly one solution, or infinitely many solutions (just like for one linear equation in one variable). 1) lf the ratio of the coefficients on the x’s is unequal to the ratio of the coefficients on the y’s (in the same order), then there is exactly one solution.

WebSolution The correct option is B 3 2 - 2 i Explanation for the correct option z - z = 1 + 2 i Let z = x + i y z = x 2 + y 2 z - z = 1 + 2 i ⇒ x 2 + y 2 - ( x + i y) = 1 + 2 i ⇒ x 2 + y 2 = 1 + x + i ( 2 + y) Comparing real and imaginary parts of both sides ⇒ 2 + y = 0 ⇒ y = - 2 1 + x = x 2 + y 2 Squaring both sides WebThe equation y2 = x3 + 45 has no integral solutions. Proof. Assume there is an integral solution. If yis odd then x3 = y2 45 1 45 4 mod 8, which is impossible. Therefore y is even, so xis odd. Reducing the equation mod 4, 0 x3 + 1 mod 4. Since x3 xmod 4 for odd x, x 3 mod 4. Also, yis not a multiple of 3. If 3 jythen the equation y2 = x3 + 45 rd sharma class 10 triangles chapter pdf https://bruelphoto.com

Given, z 2+ z=0 or, x 2−y 2+2ixy+x−iy=0 or, (x 2−y 2+x)+i(2xy−y)=0 Comparing the real and imaginary part we get, x … WebThe equations are x+2z= 4 (mod 5), y+z= 3 (mod 5). There are multiple solutions — in fact, since there is one free variable (z), there will be 5 distinct solutions mod 5. As is customary when a system has multiple solutions, I’ll write the solution in parametric form. Set z= t. Then x+2t= 4, so x= 3t+4 (by adding 3tto both sides).
