helpppp meeeeeeeeeeeeeeeeeeeeeeeeee pfv

Answer 1

Explicação passo-a-passo:

$a)15 + ( + 5)2 \\ 15 + 5 \times 2 \\ 15 + 10 \\ 25$

$b)32 - ( + 7)2 \\ 32 - 7 \times 2 \\ 32 - 14 \\ 18$

$c)18 + ( - 5)2 \\ 18 + ( - 5) \times 2 \\ 18 - 10 \\ 8$

$d)40 - ( - 2) \times 3 \\ 40 + 2 \times 3 \\ 40 + 6 \\ 46$

$e)( - 8)2 + 14 \\ ( - 8) \times 2 + 14 \\ - 16 + 14 \\ - 2$

$f)( - 7)2 - 80 \\ ( - 7) \times 2 - 80 \\ - 14 - 80 \\ - 94$

$g) (-2)5+ 21 \\ ( - 2) \times 5 + 21 \\ - 10 + 21 \\ 11$

$h)(-3)3 - 13 \\ ( - 3) \times 3 - 13 \\ - 9 - 13 \\ - 22$

$i)(-4)2 + (-2)4 \\ ( - 4) \times 2 + ( - 2) \times 4 \\ - 8 - 8 \\ - 16$

$j)(-3)2 + (-2)3 \\ ( - 3) \times 2 + ( - 2) \times 3 \\ - 6 - 6 \\ - 12$

$k)(-1)6 + (-3)3 \\ ( - 1) \times 6 + ( - 3) \times 3 \\ - 6 - 9 \\ - 15$

$l)(-2)3 + (-1)5 \\ ( - 2) \times 3 + ( - 1) \times 5 \\ - 6 - 5 \\ - 11$
