To calculate 6 squared plus 8 squared, you first need to square each number individually. 6 squared is 6 x 6, which equals 36. 8 squared is 8 x 8, which equals 64. Adding these two results together, you get 36 + 64, which equals 100. So, 6 squared plus 8 squared is 100.

The missing number is 49. This is why: 1 plus 2 equals 3, then 3 squared is 9. 2 plus 3 equals 5, then 5 squared is 25. Therefore, the missing number must be 49 to make the number sentence (3 plus 4 equals 7, then 7 squared is 49) true.

Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
b= 10
X = √63
b = 14324.80366
