\(5678g=5,678kg=5678g\)

\(45kg56dag=45\cdot1000+56\cdot10=45560g\)

\(19x+22\times3:14=11-6^2\)

\(\Leftrightarrow19x+66:14=11-36\)

\(\Leftrightarrow19x+\dfrac{33}{7}=-25\)

\(\Leftrightarrow19x=-25-\dfrac{33}{7}\)

\(\Leftrightarrow19x=-\dfrac{208}{7}\)

\(\Leftrightarrow x=\dfrac{-\dfrac{208}{7}}{19}\)

\(\Leftrightarrow x=-\dfrac{208}{133}\)

=8.25

đúng chắc chắn đó

8.25

\(=\frac{11.3^{29}-3^{30}}{2^2.3^{28}}=\frac{11.3^{29}-3^{29}.3}{2^2.3^{28}}=\frac{3^{29}\left(11-3\right)}{2^2.3^{28}}=\frac{3^{29}.2^3}{2^2.3^{28}}=\frac{3.2}{1.1}=6\)

x=6

nếu đúng cho mình nhé!

lim x → - 2 2 x 3   +   15 x   +   2 2   =   - ∞

1234+2345=3579

3456+5678=9134

5678+7891=13569

1234+2345=3579

3456+5678=9134

5678+7891=13569

k mk nha mn 

 bài này làm thế này: 1234^5678>1000^5678 ( do 1234>1000 ) Mà 1000^5678>1000^5000=1000^(2.2500)=100000...

5678        1234

1234 = 1234
