Câu 1

=> 38-x=0 hoặc x+25=0

TH1

38-x=0

x=38

TH2

x+25=0

x=-25

Vậy x e { 38;-25}

Câu 2

= 4544 + 32 . (-7 - 13)

= 4544 + 32 . (-20)

= 4544 + (-640)

= 3904

@minhnguvn

Câu 1 :

\(\left(38-x\right).\left(x+25\right)=0\)

\(\orbr{\begin{cases}38-x=0\\x+25=0\end{cases}}\)

\(\orbr{\begin{cases}x=38\\x=-25\end{cases}}\)

Câu 2 :

\(71.64+32.\left(-7\right)-13.32\)

\(=4544+32.\left(-7\right)-13.32\)

\(=4544+32.\left(\left(-7\right)-13\right)\)

\(=4544+32.20\)

\(=4544+52\)

\(=4596\)

Câu 1

x = 38 và x = - 25

Câu 2

71 . 64 + 32 . (-7) - 13 . 32

= 71 . 2 . 32 + (-7) . 32 - 13 . 32

= (142 - 7 - 13) . 32

= 3904
