Answer:

x = 6 x 6

y = 4 x 4

Step-by-step explanation:

This is because...

x^2 means "x cubed", meaning multiply it by itself. Same for y.

Now the math...

6 x 6 = 36

4 x 4 = 16

Math 2

Without rounding, we find the true sum of 36 + 16 = 52.

Therefore,

x^2 + y^2 = 52

Explanation:

Starting with the first option, the square root of 12 and 8 isn’t a perfect square so it definitely can’t be reduced to 3/2.

It is the same for the second option as well.

Third option :
Root of 36 is 6
Root of 16 is 4

6/4 = 3/2

Fourth option:
Root of 81 is 9
Root of 36 is 6

9/6 = 3/2

Answer:

Therefore, the third and fourth options are the correct choices.

Hope this helped!
