Answer 1

Resposta:

Explicação passo a passo:

1.

1,25+[5/3:(-1/2-1/3)]^-2=

125/100+[5/3:(-3/6-2/6)]^-2=

3/4+[5/3:(-5/6)]^-2=

3/4+[5/3.-6/5]^-2=

3/4+[-6/3]^-2=

3/4+[-2]^-2=

3/4+[-1/2]^2=

3/4+1/4=

4/4=

1

2.

V0,64+[(1/4.1/2+2^2):1/4]=

V64/100+[(1/8+4):1/4]=

8/10+[(1/8+32/8):1/4]=

8/10+[33/8:1/4]=

8/10+[33/8.4/1]=

8/10+[132/8]=

8/10+ 33/2=

8/10+165/10=

173/10=

17,3
