**Show you know:**

a) Identify a whole number with a square root between 8 and 9.

b) How many whole numbers can you find that have a square root between 8 and 9? show you work.

a) First I changed the number 8 to 64 (8x8) and 9 to 81 (9x9).

64 ? 81

64 73 81

b) There are 16 whole numbers I found.

65 = 8.0

66 = 8.12

67 = 8.18

68 = 8.24

69 = 8.30

70 = 8.36

71 = 8.42

72 = 8.48

73 = 8.54

74 = 8.60

75 = 8.66

76 = 8.71

77 = 8.77

78 = 8.83

79 = 8.88

80 = 8.94

I used perfect squares to find these.

P.s I'm not sure if I'm right so can you guys help me out? Just post your answers at the comment section and I'll take a look at them.

Good job Kevin! I got the same answers as you except, I didn't write in the square roots. For a) I wrote 70. I like how you used some colour, but next time maybe just use the colour to emphasize important words. Good job!(:
