Answer 1

Answer:

If 3x3= 12, 4x4= 20, 5x5=30 ,8x8=42

Step-by-step explanation:

Answer 2

Given :

3x3 =12, 4x4=20 ,5x5=30.

To Find:

The value of 8 x 8.

Solution:

The question can be solved by developing a common logic between each term.

• It is given that the value of 3 x 3 = 12, It is obtained using the logic,

=> 3 x 3 = $3^2$ + 3 = 12,

• The second term 4 x 4 = 20 is obtained using the logic,

=> 4 x 4 = $4^2$ + 4 = 20,

• The third term 5 x 5 = 30 is obtained using the logic,

=> 5 x 5 = $5^2$ + 5 = 30,

• Using the given logic the value of 8 x 8 can be found using the same logic,

=> 8 x 8 = $8^2$ + 8 = 72.

Therefore, the value of 8 x 8 is 72.
