632  =     3,969
 
6302 = (63×10)2  = 63 × 10 × 63 × 10  = 63 ×63 × 10 × 10  
                                                            = 3,969   × 100
                                                             = 396,900

Hey, Barbara
 
Just to let you know that you made a BOOBOO: it is 396,900..Hey, I happens to all of us.  In fact, I did a problem today that took me 1/2 hour to type (I type slow, even slower on an Ipad) and, yes you guessed it, it was all wrong.
