4 x4 x4=64 + 13=77- - 4=81+(14x14=196)=277
14*13=182
13 + 14 = 27.
-27
6 + 13 + 2 + 12 + 7 + 14 = 54
3² + 20 ÷ 2² = 9 + (20 ÷ 4) = 14.
14 squared = 196, so you're looking for the sqrt of double that, ie 392, which is almost exactly 19.8
14 + 13 + 9 = 36
13 + 14 = 27
14*13=182
14 + 5 + 13 + 4 + 9 = 45
13 + 14 = 27.
134
