Question

1 – Resolva as seguintes operações de monômios:
c) 3a – (- 2a) =
d) 8z + (- 6z) =
e) 3t – 4t –(3t) =
f) (2s – 3s) + 4s -2s =
g) 18 – 56 + (-2 + 56) =
h) 22 – (23 – 5) =
i) 3xy - 8xy + 32xy =
j) 23xy + 21xy – (12xy + 23xy) =

Me ajuda porfavor de

Answer 1

Olá!!  :)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Para resolver operações entre monômios semelhantes devemos calcular os coeficientes numéricos e repetir a parte literal .

Vamos lá!!

$\sf ITEM \ (C): \\\\ 3a \ - \ (-2a) \\\\ 3a \ + \ 2a \\\\ \boxed{\sf 5a} \\\\\\\\ ITEM \ (D): \\\\ 8z \ + \ (-6z) \\\\ 8z \ - \ 6z \\\\ \boxed{2z} \\\\\\\\ ITEM \ (E): \\\\ 3t \ - \ 4t \ - \ (3t) \\\\-t \ - \ 3t \\\\ \boxed{\sf -4t} \\\\\\\\ ITEM \ (F) : \\\\ (2s \ - \ 3s ) \ + \ 4s \ - \ 2s \\\\-s \ + \ 2s \\\\ \boxed{\sf \ s \ }$

$\sf ITEM \ (G):\\\\18\ - \ 56 \ + \ (-2 \ + \ 56) \\\\ -38 \ + \ 54\\\\ \boxed{ \sf \ 16 \ } \\\\ \\\\ ITEM \ (H): \\\\ 22 \ - \ (23 \ - \ 5) \\\\ 22 \ - \ 18 \\\\ \boxed{ \sf \ 4 \ } \\\\ \\\\ ITEM \ ( \ i \ ) : \\\\ 3xy \ - \ 8xy \ + \ 32xy \\\\ -5xy \ + \ 32xy \\\\ \boxed{ \sf \ 27xy \ } \\\\ \\\\ ITEM \ (J): \\\\ 23xy \ + \ 21xy \ - \ (12xy \ + \ 23xy) \\\\ 44xy \ - \ 35xy \\\\ \boxed{ \sf \ 9xy \ }$
