Answer:
20.5
Step-by-step explanation:
4(2)=8
3(4)=12
8+12=20
20+0.5= 20.5
The evaluation of the expression in x = 2 and y = 4 gives an outcome equal to 48.
How to evaluate an expression?
Here we need to evaluate:
x^4 + 0.5*y^3
for x = 2 and y = 4.
This means that we need to replace these variables by the given numbers, so we will get:
2^4 + 0.5*4^3
Now we just solve the operation, it gives:
2^4 + 0.5*4^3 = 16 + 32 = 48
