Well, darling, the square root of x to the 8th power is x to the 4th power. It's like cutting a cake into 8 equal pieces and then taking the square root to get 4 pieces. Simple math, just like how I like my martinis – straight to the point.
-6x3 + 4x7 - 0.8x2 + x4 - 5x5 = 4x7 - 5x5 + x4 - 6x3 - 0.8x2 = x2 (4x5 - 5x3 + x2 - 6x - 0.8)
20" x 30" x4"
75 2'x4'=8' squared 20'x 30'= 600' squared 600/8=75

10/x3 = 10 x-3d/dx(10x-3) = -30 x-4 = -30/x4

sqrt(x4) = x4/2 = x2

x times x times x times x = x4
(x2 + y2)(x + y)(x - y) = x4 - y4.
It is x4 + 11x3 + 41x2 + 61x + 30.
