1.20²-18²×3³= 2.√144= 3.12²+9²×√225= 4.√16×25= 5.16²×√256= 6.√2500-√1600= 7.√9×√64:√4= 8.6×.....=325 9.20²×4²+√169= 10.√36×39+√225+256= 11.√27×12²-15= 12.√64×81

1. 20^2 = 20 x 20 = 400
18^2 = 18 × 18 = 324
3^3 = 3 × 3 × 3 = 27
jadi
400 - (324 × 27)
400 - 8748
-8348

2. akar 144 = x
144 = x^2
12^2 = x^2
12 = x

3. 12^2 = 144
9^2 = 81
akar 225 = 15
jadi
144 + (81 × 15)
144 + 1215
1359

1. 400 - 324 x 27 = 2.052
2. √144 = 12
3 144 + 81 x 15 = 3375
4. 4 x 25 = 100
5. 256 x 16 = 4.096
6. 50 - 40 = 10
7. 3 x 8 : 2 = 12
8. 6 x 54,167 = 325
9. 400 x 16 + 13 = 6413
10. 6 x 39 + 15 + 256 = 505
11. 9 x 144 - 15 = 1281
12. 8 x 81 - 3 x 16 = 600
13. 55 x 3 = 165
14. 300 - 9 = 291
15. 81 - 64 = 17
