Question 757458
Finding or understanding square of a number is not a trick.  The concept is extremely clear:  If n is a number, then {{{n*n}}} is the square.  If N is a number, then {{{N*N}}} is a square.  If y is a number, then {{{y*y}}} is a square.  

Using the number, 43, the square of 43 is {{{43*43=1849}}}.


Understand carefully, no whole number squared will give 43.  Also, no rational number squared will give 43.
