Answer:
The output will be: 10
Step-by-step explanation:
Let us look at the code line by line
CLS
This line will clear the screen before output.
LET A = 10
This line will assign the value 10 to A
LET B=20
This line will assign the value 20 to B
LET C = (A+B)/3
This line will first calculate the value of sum of A and B, divide it by 3 and then store it in C.
The value 10 will be stored in C
LET D = C^2
This line will calculate the square of value of C and store it in D
So the value in D will be: 10^2 = 100
PRINT C
This will print the value of C on screen.
The output will be: 10
