The negative power of a number is the reciprocal of its positive power, the negative power of a positive number is positive, the negative even power of a negative number is positive, and the odd power is negative. The power of 0 of any number except 0 is equal to 1, and the power of 0 is meaningless. A negative power is the reciprocal first and then the power.

Simplification: 1.5-1/3 power is 3/2 power; The zeroth power of (-6/7) =1; 0.25 of 8 equals 0/4 of 65438+8, and 8 equals 2? , so 0.25 of 8 is equal to 3/4 power of 2, multiplied by 2 power of 1/4, the cardinal number 2 is unchanged, and the index is 3/4+ 1/4= 1, so it is 2; The zeroth power of (the cube root of 2 times the square root of 3) = 1, and the final simplified 1/3 power (-2/3) is the third power of 3/2.

The first and fourth cancel each other out, the second =2 and the third = 1, so 2+ 1=3.
