I HAVE TO FIND THE SQUARE ROOT OF 52. FIRST I FIND THE PERFECT SQUARES. 49 AND 64 AND MY PERFECT SQUARES BECAUSE,

7*7=49
8*8=64
THEN YOU FIND THE MIDDLE NUMBER WITCH IS 56.5/7.5, 52 IS CLOSER TO 49 THEN 64 SO IT’S GOING TO BE LESS THAN 7.5 BUT MORE THAN 7. I CAN NOW ELIMINATE FROM 7.1,7.2,7.3,7.4, AND I ELIMINATE 7.1 AND 7.4. THE SQUARE ROOT IS APPROXIMATELY 7.22, I CHECKED ON THE CALCULATOR AND IT’S 7.21.
