1. 0,7^2 + 0,11 = 7/10 * 7/10 + 0,11 = 49/10 + 11/100 = 501/100 = 5,01
2. 0,2^3 - 0,008 = 2/10 * 2/10 * 2/10 - 0,008 = 8/1000 - 8/1000 = 0
3. (2/3)^3 = 2/3 * 2/3 * 2/3 = 8/27
4. (1/4)^2 * 16 = 1/4 * 1/4 * 16 = 1/16 * 16 = 1
5. (2 1/3)^2 * 9 = 7/2 * 7/2 * 9 = 14/4 * 9 = 126/4 = 31 2/4 = 31,5
6. (-2 1/3)^2 * (-9)^2 = -7/3 * -7/3 - 81 = 49/9 * 81 = 3969/81 = 49
7. 1,1^2 - 1 = 11/10 * 11/10 - 1 = 121/100 - 100/100 = 21/100 = 0,21
8. 0,11^2 * 10 = 11/100 * 11/100 *10 = 121/10000 * 10 = 1210 / 10000 = 121/1000 = 0,121
9. 1^23 + 2^4 + 3^2 + 0^32 = 1 + 16 + 9 + 1 = 27.
