9 and 36
Square root of -45 = (-45)1/2 = (-3x3x5)1/2 = 3(-5)1/2 = 351/2i
The formula for finding the nth square number is n^2. Therefore, the 3rd square number is 3^2 = 9, and the 6th square number is 6^2 = 36. To find the sum of the 3rd and 6th square numbers, you add them together: 9 + 36 = 45. So, the sum of the 3rd and 6th square numbers is 45.
