Question

[(4 · 3 – 6) + (8 · 3 – 15 ÷ 3)] · [(9 ÷ 3 + 3 · 9) ÷ (6 – 3)] – [10. - (5. 5 -7) + (20 ÷ 2 a la potencia 2 )].

Answer 1

Respuesta:

[(4 · 3 – 6) + (8 · 3 – 15 ÷ 3)] · [(9 ÷ 3 + 3 · 9) ÷ (6 – 3)] – [10. - (5•5 - 7) +(20÷2²)]

= [(12 – 6) + (8 · 3 – 15 ÷ 3)] · [(9 ÷ 3 + 3 · 9) ÷ (6 – 3)] – [10. - (5•5 - 7) +(20÷2²)]

= [(12 – 6) + (8 · 3 – 15 ÷ 3)] · [(9 ÷ 3 + 3 · 9) ÷ (6 – 3)] – [10. - (5•5 - 7) + (20÷4)]

= [(12 – 6) + (24 – 15 ÷ 3)] · [(9 ÷ 3 + 3 · 9) ÷ (6 – 3)] – [10. - (5•5 - 7) + (20 ÷ 4)]

= [(12 – 6) + (24 – 5)] · [(9 ÷ 3 + 3 · 9) ÷ (6 – 3)] – [10. - (5•5 - 7) + (20 ÷ 4)]

= [(12 – 6) + (24 – 5)] · [(3 + 3 · 9) ÷ (6 – 3)] – [10. - (5•5 - 7) + (20 ÷ 4)]

= [(12 – 6) + (24 – 5)] · [(3 + 27) ÷ (6 – 3)] – [10. - (5•5 - 7) + (20 ÷ 4)]

= [(12 – 6) + (24 – 5)] · [(3 + 27) ÷ (6 – 3)] – [10. - (25 - 7) + (20 ÷ 4)]

= [(12 – 6) + (24 – 5)] · [(3 + 27) ÷ (6 – 3)] – [10. - (25 - 7) + 5]

= [6 + (24 – 5)] · [(3 + 27) ÷ (6 – 3)] – [10. - (25 - 7) + 5]

= [6 + 19] · [(3 + 27) ÷ (6 – 3)] – [10. - (25 - 7) + 5]

= [6 + 19] · [30 ÷ (6 – 3)] – [10. - (25 - 7) + 5]

= [6 + 19] · [30 ÷ 3] – [10. - (25 - 7) + 5]

= [6 + 19] · [30 ÷ 3] – [10. - 18 + 5]

= [6 + 19] · [10] – [10. - 18 + 5]

= [6 + 19] · [10] – [ -180 + 5]

= [6 + 19] · [10] – [ -175]

= [27] · [10] – [ -175]

= [270] – [ -175]

= [270] + 175

= 445
