Calculati 1minus{(1/2)tot la puterea a 3a +[(2/3minus5/2)tot la puterea a2a + 1/6 minus (93/90 minus39/45)]:3/2}×6. va rog mult ami trebuie acum urgent​

Answer 1

Răspuns:

1-{$(1/2)^{3}$+[(2/3-5/2$)^{2}$+1/6-(93/90-39/45)]:3/2}×6

1-{1/8+[(4/6-15/6$)^{2}$+1/6-(93/90-78/90)]:3/2}x6

1-{1/8+[(-11/6$)^{2}$+1/6-15/90:3/2]}x6

1-[1/8+(121/36+1/6-30/270)]x6

1-[1/8+(121/36+6/36-1/9)]x6

1-[1/8+(121/36+6/36-4/36)]x6

1-(1/8+123/36)x6

1-(9/72+246/72)x6

1-255/72x6
