Let's know that the absolute value of A-4 and the second power of (B + 1) are opposite to each other. Find the negative B power of a minus the a power of B. the second power of (B-A) minus the 25 power of B

Let's know that the absolute value of A-4 and the second power of (B + 1) are opposite to each other. Find the negative B power of a minus the a power of B. the second power of (B-A) minus the 25 power of B

∵|a+4|≥0,（b-1）²≥0
∴a+4=0,b-1=0
a=-4,b=1
The negative B power of a minus the a power of B
=The negative fourth power of (- 4) - the negative fourth power of (- 1)
=Minus five quarters
The second power of (B-A) minus the 25th power of B
=The square of (- 1 + 4) - (- 1) 25th power
=10
OK? Solved!
