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
