I assume by 2 cubed you mean 2^3. That equals 2 * 2 * 2 which equals 8. 8 is rational, so yes.
No because 3 cubed is 27 which is a rational number
2 cubed is 4 6 cubed is 36 9 cubed is 81 & 8 cubed is 64
(a-b)(a^2 + ab + b^2)
what is the rational number for 2/25
No, 2 cubed is not the same as 3 squared. 23 = 8 32 = 9
Yes.
Yes.
No.

8
Because the cube root of 343 is an integer.
2 cubed = 2*2*2 =8. 8+8+8= 24
2 cubed = 8
-27 is one possible answer.
X 2 cubed
2 x 2 x 2 = 2 cubed
