- (- 3) & # 179; × (- 3) & # 178; is this the power calculated first and then the sign changed?
What should be the process first?

It's the power first! Absolutely right

The power calculation of (a + b) (B + a) &_; (B + a) & # 178; + (a + b) & # 178; &; (- a-b) & # 178;)

（a+b）（b+a）•（b+a）²+（a+b）²•（-a-b）² =（b+a）（b+a）•（b+a）²+（a+b）²•（a+b）² =（b+a）^(1+1+2)+(a+b)^(2+2)=(b+a)^4+(a+b)^4=2(a+b)^4...

Look at the following two
Observe the following two lines:
-4,8,-16,32,-64,.
0,12,-12,36,-60,.
(1) The first five numbers in the first row are expressed by power;
(2) Write the 99th and 100th number in the first line;
(3) What is the relationship between the number of the second row and the number of the first row

(1)-2^2;2^3;-2^4;2^5;2^6
(2)-2^99;2^100
(3) The first line plus four equals the second line
