Question

"calcule o valor numerico da expressão a cima"
alguem pode me ajudar pfvr?​

Answer 1

$e)5 \times 15 = 75$

$f) - 6 \times (- 3) = \\ 6 \times 3 \\ 18$

$g)3 \times ( - 2) + 7 = \\ - 6 + 7 \\ 1$

$h)4 \times 5 - 2 = \\ 20 - 2 \\ 18$

$i)4 \times 1 + 2 \times 3 + 5 = \\ 4 + 6 + 5 \\ 15$

$j) {1}^{3} + 5 \times {2}^{3} = \\ 1 + 5 \times 8 \\ 1 + 40 \\ 41$

Answer 2

Resposta:

e)5×15=75

\begin{gathered}f) - 6 \times (- 3) = \\ 6 \times 3 \\ 18\end{gathered}

f)−6×(−3)=

6×3

18

\begin{gathered}g)3 \times ( - 2) + 7 = \\ - 6 + 7 \\ 1\end{gathered}

g)3×(−2)+7=

−6+7

1

\begin{gathered}h)4 \times 5 - 2 = \\ 20 - 2 \\ 18\end{gathered}

h)4×5−2=

20−2

18

\begin{gathered}i)4 \times 1 + 2 \times 3 + 5 = \\ 4 + 6 + 5 \\ 15\end{gathered}

i)4×1+2×3+5=

4+6+5

15

\begin{gathered}j) {1}^{3} + 5 \times {2}^{3} = \\ 1 + 5 \times 8 \\ 1 + 40 \\ 41\end{gathered}

j)1

3

+5×2

3

=

1+5×8

1+40

41
