Answer 1

Respuesta:

Explicación paso a paso:

1)1/5 - {3/4 - [1/8 - (1/2 - 1/3) ] }=1/5-{3/4-[1/8-1/2 +1/3]}=1/5-{3/4- 1/8+ 1/2 -1/3}

=1/5-3/4+1/8-1/2+1/3 =24-30+15-60+40 /120 =-11/120

2) (2+2/3÷1/5 ×4/7)÷(47/63÷2/5)=(2+2/3 ÷4/35)÷(47/63 ×5/2)=

(2+2/3 × 35/4)÷(235/126) =(2+70/12)÷(235/126)=(24+70 /12)÷(235/126)=

94/12 × 126/235 = 2/2 × 21/5 = 42/10

3) (2 + 2/5) ÷ (18/5) - 7/9 ÷ 4/3 =( 10+2 /5)÷(18/5)-7/9×3/4 =12/5÷18/5 -21/36 =

12/5 ×5/18 -21/36 = 2/3-21/36= 24-21 /36 =3/36 =1/12

4)(2/3 - 4 1/5) ÷ (3 1/3 + 3/7) × 11 2/7 = (2/3-21/5)÷(10/3 +3/7)×79/7=

(10-63/15)÷(70+9/21) ×79/7= -53/15 ÷ 79/21 x79/7= -53/15×21/79×79/7=-53/5

5)2/5 × (3/5)³ - ⁵√- 1/32 + [(- 1/3)²]²=2(3)⁴/5⁴ +1/2 +1/3⁴ = 60.623/101250
