If a problem is not a perfect square, then you will need to use another method to solve the problem. In this case, you can use the squaring property to solve for the square root of 7 squared + 3. The squaring property states that if a is a real number, then (a + b)2 = a2 + 2ab + b2. In this case, we can let a = 7 and b = 3, so that (7 + 3)2 = (7)2 + 2(7)(3) + (3)2. Now, we can substitute this expression into the original problem to get: √(7)2 + 2(7)(3) + (3)2 + 3. Using the distributive property, we get: √(49 + 42 + 9) + 3. Simplifying this, we get: √100 + 3 = 10 + 3 = 13. Therefore, the square root of 7 squared + 3 is 13.
