Answer 1

Respuesta:

a) 7/8+[(1,5-1/2):2/5]^2-1/4

7/8+[(15/10-1/2):2/5]^2-1/4

7/8+[(3/2-1/2):2/5]^2-1/4

7/8+[2/2:2/5]^2-1/4

7/8+[1:2/5]^2-1/4

7/8+[5/2]^2-1/4

7/8+25/4-1/4

7/8+50/8-2/8

57/8-2/8

55/8

b) 12,2+(1/4-0,5^2+3/14x$\sqrt{49/25}$)^2+5

122/10+(1/4-0,25+3/14x7/5)^2+5

122/10+(1/4-25/100+3/10)^2+5

122/10+(1/4-1/4+3/10)^2+5

122/10+(3/10)^2+5

122/10+9/100+5

1220/100+9/100+500/100

1729/100

c) 0,5+{[(4/5x4,5)-17/10]x3/19}+$\sqrt[3]{27/64}$

5/10+{[(4/5x45/10)-17/10]x3/19}+3/4

1/2+{[(4/5x9/2)-17/10]x3/19}+3/4

1/2+{[18/5-17/10]x3/19}+3/4

1/2+{[36/10-17/10]x3/19}+3/4

1/2+{19/10x3/19}+3/4

1/2+3/10+3/4

10/20+6/20+15/20

31/20

d) {[($\sqrt{9/25+8/5}$)x15/14]^3:2,25}-$\sqrt[4]{81/16}$

{[($\sqrt{9/25+40/25}$)x15/14]^3:225/100}-3/2

{[($\sqrt{49/25}$)x15/14]^3:9/4}-3/2

{[7/5x15/14]^3:9/4}-3/2

{[3/2]^3:9/4}-3/2

{27/8:9/4}-3/2

3/2-3/2

0

e) [11/5:(0,2+5,3)]^2-(16/15x3/20)

[11/5:(5,5)]^2-4/25

[11/5:55/10]^2-4/25

[2/5]^2-4/25

4/25-4/25

0
