58751 - (10425 + y) = 3828 : 12
58751 - 10425 - y = 319
48326 - y = 319
y = 48326 - 319
y = 48007
Vậy y = 48007
5.(\(x+35\)) = 515
\(x+35\) = 515 : 5
\(x+35\) = 103
\(x\) = 103 - 35
\(x\) = 68
Vậy \(x=68\)
48751-(10425+y)=3828:12
48751-(10425+y)=319
10425+y=48751-319
10425+y=48432
y=48432-10425
y=38007
4x-20=25-2
4x-20=23
4x=23 + 20
4x=28
x= 28:4
x=7
48751-(10425+x)=319
10425+x=48751-319
10425+x=48432
x=48432-10425
x=38007
(2x-5)+17=6
2x-5=6-17
2x-5=-11
2x=-11+5
2x=-6
x=-6:2
x=-3
(2x - 5) + 17 = 6
(2x - 5) = 6 -17
2x - 5 = -11
2x = (-11) + 5
2x = -6
x = -6 : 2
x = -3
a)\(x^{15}=x\Rightarrow x\in\left\{0;1\right\}\) d)Là ý b
b)\(\left(2x+1\right)^3=125\\ \left(2x+1\right)^3=5^3\Rightarrow2x+1=5\\ 2x=4\\ x=2\) e)\(\left(x-3\right)^2=25\\ \Rightarrow\left(x-3\right)^2=5^2\\ \Rightarrow\hept{\begin{cases}x-3=5\Rightarrow x=8\\x-3=-5\Rightarrow x=-2\end{cases}}\)
c)\(\left(x-5\right)^4=\left(x-5\right)^6\\ \Rightarrow x-5\in\left\{0;1\right\}\Rightarrow x\in\left\{5;6\right\}\)
\(48751-\left(10425+y\right)=3828:12\)
\(\Rightarrow\) \(48751-\left(10425+y\right)=319\)
\(\Rightarrow\) \(10425+y=48751-319\)
\(\Rightarrow\) \(10425+y=48432\)
\(\Rightarrow\) \(y=48432-10425\)
\(\Rightarrow\) \(y=38007\)
