Answer:
a) square numbers
b) 9
Explanation:
A square number is a number that can be made by multiplying a whole number by itself(49 is a square number because 7*7=49, 64 is a square number because 8*8=64). The square root of 36 is 6. The square root of 25 is 5. The square root of 16 is 4. Thus, following the pattern, the square root of 9 is 3.
