WebIn the case x + y = x y = 3, we have x 4 + y 4 = 3 4 − 4 ⋅ 3 ⋅ 3 2 + 2 ⋅ 3 2 = − 9 A different approach is to compute x and y, which are the roots of z 2 − 3 z + 3 = 0, so we can use x = 3 + i 3 2, y = x ¯ = 3 − i 3 2 The modulus of x and y is x x ¯ = 3, so x = 3 ( 3 2 + 1 2 i) = 3 e i π / 6, y = 3 ( 3 2 − 1 2 i) = 3 e − i π / 6 Therefore WebQuestion If x=9 1/39 1/99 1/27...∞,y=4 1/34 −1/94 1/274 −1/81...∞, and z= r=1∑∞ (1+i) −r, then arg (x+yz) is equal to A 0 B π−tan −1(3 2) C −tan −1(3 2) D −tan −1( 32) Medium Solution Verified by Toppr Correct option is C) x=9 31+ 3 21+ 3 31...∞ ⇒x=9 1− 3131 ⇒x=9 21 ⇒x=3 y=4 31− 3 21+ 3 31...∞ ⇒y=4 1+ 3131 ⇒y=4 41 ⇒y=2 21 ⇒y= 2

WebJul 9, 2024 · So substituting the values for the elementary symmetric polynomials that we found, we find that x, y and z are the three roots of: t3 −t2 − 1 2t − 1 6 = 0. or if you prefer: 6t3 − 6t2 −3t −1 = 0. In theory we could solve this using Cardano's method and directly evaluate x4 +y4 + z4, but the methods used above are somewhat easier.
