-What is the sum of the opposite number of 8 and 3 and the reciprocal of the negative third? We need to test. It's negative 8

-8+（-3）+3

Given that a and B are opposite to each other, C and D are reciprocal to each other, and the square of x = 9, find X - {(a + B-Cd) to the third power}
Given the absolute value of 2a-3 + the square of (3b + 2) = 0, find the value of 100 power of a * 101 power of B

X = + 3 or - 3
a+b=0
cd=1
The third power of (0-1)
=-1
3-（-1）=4,-3-（-1）=-2
a=3/2,b=-2/3
ab=-1
（-1）^100*-2/3
=1*-2/3
=-2/3
