Question

Simplify (root 3 + root 5) the whole sq and (root 5 - root 2) the whole sq.

Answer 1

Root 3 + root 5 =1.732+2.236=3.968 
square it up you'll get 15.745
you can also apply algebraic identity that is a+b whole square 

root 5-root 2= 2.236-1.414=0.822
Squaring it you'll get 0.675

Answer 2

Answer:

Take any number whose leftmost digit is 1 and rightmost digit is 2 or 3

1————2 or 1———3

In between fill it up with any number of 0 or 1 in any order

The resulting number and its mirror image will have their squares as mirror images

Example

12 and 13

102, 112,103 and 113

1002, 1012, 1102 and 1112

(Replace 2 by 3 above to get 4 more numbers)

Repeat this with 5 digit or six digit numbers and so on
