Rozwiąż:
e) (2 ½-1⅓)²-(⅚)²=
f) (1½)³*(⅔)³-⅕*2⅙=
E. (2 6/12- 1 4/12)potegi2 -(5/6)potegi2=(1 2/12 *1 2/12)-(5/6*5/6)=(1 13/36)-(25/36)=24/36
F.(1 1/2*1 1/2*1 1/2)*(2/3*2/3*2/3)-1/5*2 1/6=(2 2/8)*(8/27)-1/5*2 1/6=6/9-1/5*13/6=6/9- 13/30=60/90-39/90=21/90
ufff...ale to mi zajelo czasu zeby to obliczyc...mysle ze to bedzie dobrze..licze na naj... :):):):):):)
