Answer 1

Olá,

Vamos lá,

a){68+4-2+[16×4]+(8×8+4)-2}
= {68+4-2+ 64+(64+4)-2}
= {68+4-2+ 64+ 68-2}
= 200


b){49-7+[16×4]+(100+25-36)-1}
={49-7+64+89-1}
= 194

c){8+16+[8×2]+(2×2+4)-5}
= {8+16+ 16 +( 4+4)-5}
= {8+16+ 16 + 8-5}
= 43

d){3+[3+6+[9-16]+(2+2-2)-5}
= {3+3+6 -7+ 2 -5}
= 2

Answer 2

a){68+4-2+[16*4]+(8*8+4)-2}
{68+4-2+64+(64+4)-2}=
{68+4-2+64+68-2}=
{72-2+132-2}=
{70+130}=
200

b){49-7+[16*4]+(100+25-36)-1}
{49-7+64+(125-36)-1}=
{49-7+64+89-1}=
{42+64+88}=
{106+88}=
194

c){8+16+[8*2]+(2*2+4)-5}
{8+16+16+(4+4)-5}=
{8+16+16+8-5}=
{24+16+8-5}=
{40+8-5}=
{48-5}=
43

d){3+[3+6+[9-16]+(2+2-2)-5}
{3+3+6-7+(4-2)-5}=
{3+3+6-7+2-5}=
2
