tolong dijawab .....dengan caranya +_+ ......krena besok tugasnya mau dikumpulin!!!

1.3^2 + 5^2= 3x3 + 5x5 = 9 + 25 = 31
2.10^2-1^2= 10x10 + (-1x-1) = 100 + 1 = 101
3.2^2+3^2= 2x2 + 3x3 = 4 + 9 = 13
4.2^2x3^2= (2x2) x (3x3) = 4 x 9 = 36
5.100^2 +10^2 = 100 x 100 + 10 x 10 = 10.000 + 100 = 10100
6.8^2:4^2 = (8x8) : (4x4) = 64 : 16 = 4
7.11^2-7^2= 11x11 - 7x7 = 121 - 49 = 72
8.12^2+13^2= 12x12 + 13x13 = 144 + 169 = 313
9.14^2+10^2= 14x14 + 10 x 10 = 196 + 100 = 296
10.(15^2:5^2)x9^2= (15 x 15 : 5 x 5) x 9 x 9 = (225 : 25) x 81 = 9 x 81 = 729
Semoga Membantu :)
