Question

{(3×4+5×4)-4×8+1º+(5×6-4×7)² alguém ajuda!!!

Answer 1

Resposta:

Explicação passo-a-passo:

{(3×4+5×4)-4×8+1º+(5×6-4×7)²=

3.4= 12

5x4=20

-4x8=-32

1^0=1

{(12+20)-32+1+(5×6-4×7)²

{(32)-32+1+(5×6-4×7) . (5×6-4×7)=

{32-32+1+(5×6-4×7) . (5×6-4×7)=

{+1+(5×6-4×7) . (5×6-4×7)=

{+1+(5×6-4×7) . (5×6-4×7)=

5.5= 25

5.6=30

5.-4=-20

5.7=35

6.5=30

6.6=36

6.4=24

6.7=42

4.5=20

4.6=24

4.4=16

4.7=28

7.5=35

7.6=42

7.4=28

7.7=49

Soma todos:

+1(+25+30+20+35+30+36+24+42+20+24+16+28+35+42+28+49)=

+1(+55+55+66+66+44+44+77+77)=

+1(+110+112+88+114)=

+1(+222+202)=

+1(+424)

1+425=

426
