Answer 1

Answer:

plz mark brainliest. ........

Answer 2

Answer:

(xy+8)(xy-8)

Step-by-step explanation:

x^2y^2=(xy)^2-------------------------(1)

agreed

now the question is

x^2y^2-64

so in (1)

we can say that

(xy)^2-64

we known that 8^2 =64

(xy)^2-8^2

and the identity

A^2-B^2=(A+B)(A-B)

SO HERE

A=xy

and

b=8                                                                                                  

so we can derive

(xy+8)(xy-8)

HOPE IT HELPED AND

PLS SMASH THAT THANKS,FIVE STAR RATING AND LAST BUT NOT LEAST  MARK AS BRAINLIST
