ok !

I will solve 1st part ok then you try to understand

(a

$(a ^{2} - b {}^{2} ) =$

By using identity ;

$(a {}^{2} ) {}^{2} - 2a {}^{2} b {}^{2} + (b {}^{2} ) {}^{2}$

$a {}^{4} - 2a { }^{2} b {}^{2} + b {}^{4}$

This is your answer of first part as a type of example & now watching and learning this formula you can do other parts easily

so plz mark me as brainlist ♡
