B. (Harder still) The numbers below are all square numbers. Work out what the square roots must be by: (i) (ii) working out which two known squares it falls between; and looking at the last digit to work out the possible ones digits; and working out which of the two known squares the number is closest to in order to determine which is the ones digit. (iii) Example: 2304 (i) Between 1600 (40²) and 2500 (50²), so must be 40 something Ones digit is 4, so final digit is either 2 (2x2 = 4) or 8 (8x8=64) (iii) 2304 is nearer to 50; so √2304 is 48 (ii) a) 2916 b) 5776 c)729 d) 2601 e) 8649 f)11025
