Explicación paso a paso:
5/6+[(-1/3 +3/2)×5/4]
5/6 +[(-2/6 +9/6) ×5/4]
5/6 +[7/6 ×5/4] =
5/6 +35/24 =
20/24 + 35/24= 55/24.
-5/2 -[(4/5 +2/3) x(1/2 -4/3)]
-5/2 - [(12/15 + 10/15) × (3/6 - 8/6)]
-5/2 - [22/15 × -5/6] =
-5/2 -[ 11/3 × -1/3] =
-5/2 - [- 11/9]=
-5/2 + 11/9 =
-45/18 + 22/18= - 23/18.
-8/3 × {5/4-[ 1/6 -(7/12+3/2)]}
-8/3 ×{5/4 - [1/6 -(7/12 + 18/12)]}
-8/3 ×[ 5/4 - [1/6 - 25/12]}
-8/3 × [5/4 - [ 2/12 -25/12]}
-8/3 × [5/4 - [-23/12]}
-8/3 × [5/4 +23/12}
-8/3 × {15/12 + 23/12}
-8/3 × 38/12 =
-2/3 × 38/3 = -76/9
-5/7÷ {15/14 -[ 1/2+(3/4 - 5/3)]}
-5/7 ÷ { 15/14 - [1/2 +(9/12 - 20/12)]}
-5/7 ÷ { 15/14 - [1/2 -11/12 ]}
-5/7 ÷ {15/14 -[6/12 -11/12]}
-5/7 ÷ {15/14 - [-5/12]}
-5/7÷ {15/14 + 5/12}
-5/7 ÷ {90/84 + 35/84}
-5/7 ÷ 125/84 =
-5/7 × 84/125 =
-1/1 × 12/25 = -12/25.
los dos que siguen los haces tu, guíate de los que te hice ya, así practicas y aprendes.
√1/16 -[(2/3 - 3/4)² - (5/3 + 1/2)²]
1/4 - [(8/12 -9/12)² - (10/6 + 3/6)²]
1/4 - [( -1/12)² - (13/6)²]
1/4 - [1/144 - 169/36 ]
1/4 - [1/144 - 676/144]
1/4 - 675/144 =
36/144 - 675/144=
639/144= 213/48
