pra amanhã pfvv me ajudem (COM RESOLUÇÃO)

Answer 1

a)6+7/8 : 21/4 - 5/3

=6+7/8.4/21-5/3

=6+1/6-5/3

=6+1/6-10/6

=6-9/6

=6-3/2

=12/2-3/2

=9/2

b)1/7-49/27:(7/3)³

=1/7-49/27:343/27

=1/7-49/27.343/27

=1/7-1/7=0

c)raiz quadrada de 169/81+1-1/18 . 10

=13/9+1-5/9

=8/9+1

=17/9

d)(3/4)2 . 8/9 + raiz quadrada de 1/144

=4/3+1/12

=16/12+1/12

=17/12

e)raiz quadrada de 9/16+(1/2)³-5/8

=3/4+1/8-5/8

=3/4-4/8

=3/4-2/4

=1/4

f)4. raiz quadrada de 9/64+(2/5)². 25/8

=4.3/8+4/25.25/8

=3/2+1/2

=4/2=2
