Question

4.Calculeaza:

A=(2/3 - 1/2) + 3/4
B=5/6 + (1-3/4)
C=1/3 - (5/6 - 1/2)
D=1-(2/5 + 1/10) +3/10

va rog

Answer 1

Răspuns:

A = (2/3^4 -1/2^6) + 3/4^3

A= (8/12 - 6/12 ) + 9/12

A = 2/12+9/12

A = 12/12

A = 1

B = 5/6 + (1^4 - 3/4)

B = 5/6 + (4/4 -3/4)

B = 5/6^2 + 1/4^3

B = 10/12 + 3/12

B = 13/12

C = 1/3 - (5/6-1/2^3)

C = 1/3 - (5/6 -3/6)

C = 1/3^2-(2/6)

C = 2/6- 2/6

C =0

D = 1-(2/5^2+1/10) + 3/10

D = 1-(4/10+1/10)+3/10

D=1^10-5/10+3/10

D = 10/10-5/10+3/10

D=8/10
