Answer 2

33x33=18

Given:

11x11=4, 22x22=16

To Find:

33x33

Solution:

Observe the given two products 11x11=4 and 22x22=16.

In the first product 11x11=4,

11 is multiplied by 11 resulting in 121 as a product whose digits are added as,

1+2+1=4

In the second product 11x11=4,

22 is multiplied by 22 resulting in 484 as a product whose digits are added as,

4+8+4=16

So, in 33x33, multiply 33 by 33 as

33x33=1089

Now add the digits of 1089.

1+0+8+9=18

Thus, 33x33=18.
