If la-3l and LB + 2L are opposite to each other, find a + B + 5

If la-3l and LB + 2L are opposite to each other, find a + B + 5

La-3l and LB + 2L are opposite numbers
be
a-3=0
b+2=0
be
a=3,b=-2
be
A + B + 5 = 3-2 + 5 = 6

Given that La + 1 | and lb-4 | are opposite to each other, we can find the value of a to the power of B

According to the meaning of the title
　　|a+1|+|b-4|=0；
So, a + 1 = 0; B-4 = 0;
The results show that a = - 1; b = 4;
Therefore, the power of a to the power of B = (- 1) to the power of 4 = 1

If la-1l + LB + 3L = 0, then the value of b-a-2 is () a, - 4.5
If la-1l + LB + 3L = 0, then the value of b-a-2 is () a, - 4.5b, - 2.5c, - 1.5D, 1.5b

la-1l +lb+3l=0
a-1=0→a=1
b+3=0→b=-3
b-a-1/2=-3-1-1/2=-4.5
Answer: a
