4 cubed = 4 times 4 times 4 =64
12 + 64 = 76
To find the sum of 2 cubed, 3 cubed, and 4 cubed, we calculate each value: (2^3 = 8), (3^3 = 27), and (4^3 = 64). Adding these together gives (8 + 27 + 64 = 99). Therefore, (2^3 + 3^3 + 4^3 = 99).
The sum of the first n cubed numbers is: [n*(n+1)/2]2 which is the same as the square of the sum of the first n numbers.
- 12 + 4 = - 8
sum means to add so..... 8 + 4 = 12
4
the answer of 2 cubed is 4 because 2x2=4
The sum of 8 and 4 is 12. In mathematics, addition is the operation of combining two or more numbers to find their total. In this case, when you add 8 and 4 together, you get the sum of 12.
12 + 4 = 16
The sum of the first n cubed numbers is: [n*(n+1)/2]2 which is the same as the square of the sum of the first n numbers.
- 12 + 4 = - 8
sum means to add so..... 8 + 4 = 12
12 cubed = 12 x 12 x 12 = 1728
8+4=12
8 and 4
4
4 + 12 = 16
It is: 3*(4+12) = 48
