y times y times y (or y3)
72
The GCF of y3, y7, y8 is y3
y times y times y
y cubed or y*y*y
y
y3 x y3 - y (3)3 x 3(3) - 3 9 x 9 - 3 = ? 9 x 9= 81 81 - 3 = 78 I hope that solves your problem
y5 * y3 * y = y5 * y3 * y1 = y5+3+1 = y9
Y3
y(y - 2)(y + 2)
x6 - y6 = (x3)2 - (y3)2 = (x3 + y3) (x3 - y3) = (x + y)(x2 - xy + y2)(x - y)(x2 + xy + y2)
