Question

plz help its urgent..I will mark as brainiest..

Answer 1

16a^4 - b^4

= ( 4a^2)^2 - (b^2)^2

= ( 4a^2 - b^2) (4a^2 + b^2)

= [ (2a)^2 - (b)^2] ( 4a^2 + b^2)

= ( 2a - b) (2a + b) (4a^2 + b^2)

Answer 2

Solution :-
=(16a²)²-(b²)²
=(16a²+b²) (16a²-b²)
=(16a²+b²) [(4a)²-(b)²]
=(16a²+b²) (4a+b) (4a-b) AnSwEr...
