Question

me ajudem na b, d, e, f

Answer 1

b
1/7 - 49/27 : (7/3)³ 
1/7 - 49/27 : 343/27 =
1/7 -(  49/27 * 27/343)
1/7 - 49/343 = 
mmc = 343
(49 - 49)/343 = 0/343 = 0****

d
( 3/4)² * 8/9 + V1 / 144
9/16 * 8/9 + 1/144 =
72/144 + 1/144 = 71/144 ****

e
V9 + ( 1/3)³ - 5/8 =
3 /1+ 1/27 - 5/8 =
mmc = 216
( 648 + 8 - 135 )/216 = 
 521/216  = 2 inteiros 89/216

f
4/1 * V(9)/64 + (2/5)² * 25/8 =
4/1 * 3/64 + 4/25 * 25/8 =
12/64 + 100/200
mmc = 1600
( 300 + 800 )/1600
1100/1600 = 11/6 **** ou 1 int  5/6*****
