No, answer will not be 12^3.
4^3+ 4^3+ 4^3
=4^3[1+1+1]
=4^3[3]
=4*4*4*3
=192

4^3 + 4^3 + 4^3
=64 + 64 + 64
=192
thus 12^3 is not the correct answer

4^3 + 4^3 + 4^3 is like
x^3 + x^3 + x^3 = 3x^3
So 4^3 + 4^3 + 4^3 = 3(4^3)
Let us evaluate:
4^3 = 4 x 4 x 4 = 64
4^3 + 4^3 + 4^3 = 64 + 64 + 64 = 192
3(4^3) = 3 x 64 = 192
12^3 = 12 x 12 x 12 = 1728
So 4^3 + 4^3 + 4^3 is not equal to 12^3
In the same manner
1^3 + 1^3 + 1^3 is not equal to 3^3 because
1^3 = 1
1 + 1 + 1 is not equal to 3 x 3 x 3
Hope you understand!!!!

You can not add the 4's and cube the result. What you have are 3 of the same monomial added. All you can do is count them (3) and solve one of them (64), then multiply the 3 by the 64 to get 192. Think of this as x + x + x = 3x and x = 4^3.

4^3 + 4^3 + 4^3 = 3*4^3 = (4 - 1)*4^3 = 4*4^3 - 4^3 = 4^4 - 4^3 = 256 - 64 = 192

4*4*4=64
4*4*4=64
4*4*4=64
Then add the 64 +64+64 =192
because,
4*4= 16 then times 16 by 4=64
4*4 =16 *4 = 64
4*4= 16 * 4 =64 then add them all together like this
64+ 64+64 =192
Hope that helps!

4^3=64
64+64+64= 192

No. The answer is 3*4³ = 3*64 = 192.
12³ = 1728.
