Based on the given equation, we have:
1
3³ = 4
4
x
To complete the equation, we need to find the missing number. Let's analyze the pattern:
3³ = 27
4
The pattern seems to involve cubing a number to get the value below it. In this case, 3 cubed (3³) equals 27, which is the number below 4.
Therefore, to continue the pattern, the missing number (x) would be the cube of 4:
4³ = 64
So, the missing number to complete the equation is 64.
