Answer 1

2) 64²-36²= (64-36)*(64+36)= 28*100= 2800

3) (11/3)²-(7/3)²= (11/3-7/3)*(11/3+7/3)= 4/3*18/3= 4/3*6= 8

4) (68/9)²-(40/9)²= (68/9-40/9)*(68/9+40/9)= 28/9*108/9= 28/9*12= 112/3= 37 1/3

Answer 2

2)=(64-36)(64+36)=28*100=2800

3)=( 3 2/3- 2 1/3)(3 2/3+ 2 1/3)= 1 1/3*6=4/3*6=24/3=8

4)=(7 5/9- 4 4/9)( 7 5/9 + 4 4/9)= 3 1/9*12= 28/9*12=336/12= 37 1/3
