576 + 869 + 8967 

= (576 + 869) + 8967

= 1445 + 8967

= 10412 

\(\frac{\frac{125}{8}+\frac{125}{97}+\frac{125}{576}+\frac{250}{991}}{\frac{25}{8}+\frac{25}{97}+\frac{25}{576}+\frac{50}{991}}\)=\(\frac{250.\left(\frac{1}{8}+\frac{1}{97}+\frac{1}{576}+\frac{1}{991}\right)}{50.\left(\frac{1}{8}+\frac{1}{97}+\frac{1}{576}+\frac{1}{991}\right)}\)=\(\frac{250}{50}\)=5

Nhớ tick

( - 576 ) + 400 + ( - 215 ) +176

= ( - 576 + 176) + 400 + ( - 215 )

= - 400 + 400 ( - 125 )

= 0 + ( - 125)

= - 125

(-576)+400+(-215)+176

=  (-576+176)+400+(-215)

= -400 + 400+(-215)

= 0 + (-215)

= -215

(-576)+400+(-215)+176

= (-576+176)+400+(-215)

= -400 + 400+(-215)

= 0 + (-215)

= -215

576 + 23 = 599
Học tốt!!!

599

AHIHI

bn bít hong ??????

= 599 bn nha 

\(2^{3+x}+2^x=576\)

\(\Rightarrow2^x\cdot2^3+2^x=576\)

\(\Rightarrow2^x\cdot\left(2^3+1\right)=576\)

\(\Rightarrow2^x\cdot\left(8+1\right)=576\)

\(\Rightarrow2^x\cdot9=576\)

\(\Rightarrow2^x=576:9\)

\(\Rightarrow2^x=64\)

\(\Rightarrow2^x=2^6\)

\(\Rightarrow x=6\)

Vậy $x=6$.

\(2^{3+x}+2^x=576.\)

\(2^3.2^x+2^x.1=576\)

\(2^x.\left(2^3+1\right)=576\)

\(2^x.9=576\)

\(2^x=576:9\)

\(2^x=64\)

\(2^x=2^6\)

\(\Rightarrow x=6\)

576+47+24

=(576+24)+47

=600+47
