Simplify. Do not use negative exponents in the answer. 12x2y4 3xy7 There should be a line between like a fraction but it did not copy or paste. This is the answer I got 12 x^2 y^4 = 12y^4/x^2 3xy^7 = 3x/y^7 it was wrong.

Simultaneous equation
X+y+z=1......(1) x^2+y^2+z^2=35........(2) x^3+y^3+z^3=97.........(3) solution but from 3 (x^3+y^3)=(x+y)^33xy(x+y)......(4) puting 4 into 3 bck (x+y)^33xy(x+y)+z^3=97.......(5) now from 1 x+y=1z......(6) putin 6 into 7 we have
