Question

doy coronita al que me me ayude si no saben la respuesta no contesten

Answer 1

Respuesta:

A. 2/9-[5/4+(7/5×3/2)]+2/3

2/9-[5/4+21/10]+2/3= 2/9-[67/20]+2/3= 2/9-67/20+2/3= - 443/180

B. [7/4-(3/2*7/5)]^2-1/9

[7/4-(3/2×7/5)]^2-1/9

[7/4-(21/10)]²-1/9

[7/4-21/10]²-1/9

[35-42/20]²-1/9

[-7/20]²-1/9

49/400-1/9

441-400/3600

=41/3600

C. 3/4-{2/5+[(2/5+3/5)-(1/6+1/2)]}

3/4× (2/5+ (1-2/3))

3/4× (2/5+1/3)

3/4×11/5

Simplificamos

1/4×11/5

Multiplicamos

11/20

D. [(4 / 7)³ - (1 / 4 + 4 / 3)]²

[64 / 343 - ((3 + 16) / 12)]²

[64 / 343 - 19 / 12]²

[(768 - 6517) / 4116]²

[- 5749 / 4116]²

[- 1.3967]²

1.95
