4x3+6x7 = (4x3)+(6x7) = 12+42 = 54 in the rules of calculation the times has to be done before the plus so the 6x7 must be figured out before you can add.
7^2 + 3^2 = 58
3 + 43 = 46 7 squared = 49 46 + 49 = 95

1 squared plus 8 squared or 4 squared plus 7 squared
7^2 + 3^2 = 58
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
(9x2 + 7)(9x2 - 7) = 81x4 - 49
7 Squared is 49. 10 plus 49 is 59.
3 + 43 = 46 7 squared = 49 46 + 49 = 95

No. 7 squared plus 11 squared does not equal 15 squared.
Strewth - 42 (and that was without a calculator)
