The GCF is y4
It is 24y^2.
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
x2 + y4 + x4 +y2 = x6 + y6unless you know what x and y are.* * * * *x2 + y4 + x4 + y2 ??I don't believe that this expression can be factorised or otherwise simplified.It certainly does not equal x6 + y6,for all x and all y:for example, if x = y = 1, thenx2 + y4 + x4 + y2 = 4, whilstx6 + y6 = 2;thus, they are two manifestly unequal quantities.
18xy is the GCF of 72x2y and 18xy
x-7*y*4 >> solve it * is multiply-
3-y6 = -3
x=63xy-2/x39*x2y4/x69x2x6*y4
Multiply and simplify 3^-2 x3^6
well, if 3x6 is in parentheses with the y4, then you multiply to get 18y4. After that, you go to the power of -1, which is basically dividing 1 by 18y4. The final answer would be a fraction with 1 on the top and 18y4 on the bottom.
The GCF is y6.
x=y4 /2
