7^2 + 3^2 = 58

it`s 81. Anything squared means timed the number you`re timing it with. For example. 7 squared= 7 times 7 3 squared= 3 times 3. Hope I helped! (^_^)

The greatness of 4 squared and 3 squared is expressed by the equation: 16 - 9 which equals 7.3 squared equals 3 x 3 = 94 squared equals 4 x 4 = 1616 - 9 = 7

3 + 43 = 46 7 squared = 49 46 + 49 = 95

(3 root 7) squared = (3 root 7) (3 root 7) = (3x 3) ( sq root 7 x 7) = 9 x sq root 49 = 9 x 7 = 63

3 squared = 97 squared = 49Therefore, the sum is 9 x 49 x 8.This is equal to 3528.

The number could be -8 or it could be +7.

3(x - 7)(x + 7)

7^2 - 3*7 49 - 21 28

3 squared is 9 and so 9n = 63 which means n = 7

4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)

7(x + 3)(x - 3)

seven 4 x 4 = 16 3 x 3 = 9 16 - 9 = 7

A number that is squared is a number 49 is 7 because 7 squared is 7x7=49 square root of 1=1 4=2 9=3 and so on.

3 squared = 9 9 - 2 x 1 = 9 - 2 = 7

7 squared and 3 squared. 49 - 9 = 40

6 squared

7(squared) or 7(sq)

-7 squared, which would be -49.
