Question

3,5 la puterea 2 - 1,2*{11+1,1*[6,5+2*(0,45-0,4)]} nu stiu unde gresesc dar nu mi da corect rezultatul

Answer 1

=3,5 la puterea 2-1,2*[11+1,1*(6,5+2*0,05)]
=3,5 la puterea 2-1,2*[11+1,1*(6,5+0,1)]
=3,5 la puterea =3,5 la puterea 2-1,2*(11+1,1*6,6)
=3,5 la puterea 2-1,2*(11+7,26)
=3,5 la puterea 2-1,2*18,26
=3,5 la puterea 2-21,912
=12,25-21,912=-9,662

Answer 2

3,5²-1,2*{11+1,1*[6,5+2*(0,45-0,4)]} = 12,25-1,2*{11+1,1*[6,5+2*0,05]} =12,25-1,2*{11+1,1*[6,5+0,1]} = 12,25-1,2*{11+1,1*6,6} = 12,25-1,2*{11+7,26} = 12,25-1,2*18,26 = 12,25-21,912= - 9,662
