Answer 2

Answer:

The required answer is 88.

Step-by-step explanation:

It is given that

2+2=4

3+3=10

4+4=18

5+5=28

6+6=40

The relation between them is defined as

$2+2=2^2+0=4$

$3+3=3^2+1=10$

$4+4=4^2+2=18$

$5+5=5^2+3=28$

$6+6=6^2+4=40$

$7+7=7^2+5=54$

$8+8=8^2+6=70$

$9+9=9^2+7=88$

Therefore 9+9=88.
