Y^3(Y^3-Y)=???
We know Y=3 so this, Y^3(Y^3-Y) now looks like this..
3^3(3^3-3)
For the outside
we know 3^3=27
Ex. 3x3x3=27
Break Down
3x3=9x3=27
So from Y^3(Y^3-Y)
we went to 3^3(3^3-3)
to this 27(27-3)
Now subtract 27-3=24to get you final X
27(24)= or 27*24= 648
Steps...
Y^3(Y^3-Y)
Y^3(Y^3-Y)
3^3(3^3-3)
27(27-3)
27(24)= or 27*24= 648
y times y times y (or y3)
They don't seem to different at first. But the thing is, Y3 is outdated and old. It may still have the original database of Y8, but Y3 is older. If you notice the layout of the new Y8, it is newer and more user friendly. Plus a really world-known game, Bloons Tower Defense, can't be found on Y3 easily, while Y8 brings the searches instantly. Y8 is better than Y3.

y5 * y3 * y = y5 * y3 * y1 = y5+3+1 = y9
6x+y=3
6y-y3 = 3
-y3 + 7y3
x3-y3
72
27-y3 factored completely = 24
X2+Y3+15 All you can do is simplify it.
No
y times y times y (or y3)
30
12x2 - 24x + 9y
The GCF of y3, y7, y8 is y3
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
