To find the sum of 1 cubed, 2 cubed, and 3 cubed, we can express this as:
[ 1^3 + 2^3 + 3^3 ]
Calculating each term:
– ( 1^3 = 1 )
– ( 2^3 = 8 )
– ( 3^3 = 27 )
Now, sum these values:
[ 1 + 8 + 27 = 36 ]
So, the value of the expression is 36. Great job working through this! If you need further assistance, feel free to ask!
