2. The negative 0.6 power of14 is similar to the above. First, the negative number becomes the sixth power of 14. Then press the first algorithm.

3. There is no solution to this problem, because negative numbers cannot open the root sign, and the power of-12 under the root sign is 12. If you want to use a complex number, just remember one formula,-1= the square of I, and I is a complex number. If it is half of-12, it is-12* 1/2=-6. Regarding the supplementary question, I want to say that negative numbers are different from positive numbers, and half of-12 is greater than-12 equals -6, just like you. Later, someone paid you back 6 yuan. Do you still have six dollars? For you, 6 yuan is -6. So-12* 1/2 is greater than the original number.

4. The opening of negative numbers is the same as that of positive numbers. Just note that if the square of a complex number is a multiple of 2, it will become a positive number, for example, the square of -5 equals 25, and so on. If it is a multiple of three, it will remain negative, for example, the cubic of -5 is equal to-125.

5. The negative power of a negative number is similar to the second one, that is, the decimal number is changed into an integer, which is the same.
