(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
7^2 - 3*7 49 - 21 28

7³ = 7 x 7 x 7 = 343
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! (^_^)
3 + 43 = 46 7 squared = 49 46 + 49 = 95
The number could be -8 or it could be +7.
(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

7^2 - 3*7 49 - 21 28
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
