-The value of 2011 power of 1 + 2012 power of - 1 is

-The value of 2011 power of 1 + 2012 power of - 1 is

-The power of 1 = - 1
-The power of 1 = 1
Add = 0

It is known that the square of | A-2 | and (B + 1) are opposite to each other, so we can find the power a of (1) B; (2) the power 3 of a + the power 15 of B

(1) 1
(2) 9

It is known that the second power of | A-2 | and (B + 1) are opposite to each other. Find out: (1) the a power of B; (2) the third power of a + the 15th power of B

∵ the absolute value of any number is nonnegative and the square is nonnegative
∴a-2=0,b+1=0
∴a=2,b=-1
The power of a of B = (- 1) & sup2; = 1
a³+b^15=8-1=7

What is LG (- 2) equal to? What is LG2 equal to
Wrong... Forget to type radical 5
They are LG (- 2 + radical 5) and LG (2 + radical 5)

LG (- 2) is meaningless
