\(\Leftrightarrow3x+1\in\left\{1;-1;2;-2;5;-5;10;-10\right\}\)
hay \(x\in\left\{0;-\dfrac{2}{3};\dfrac{1}{3};-1;\dfrac{4}{3};-2;3;-\dfrac{11}{3}\right\}\)
Tìm số nguyên x , biết
\(10\) ⋮ \(\left(x-1\right)\)
\(b.\left(x+5\right)\) ⋮ \(\left(x-2\right)\)
c. \(\left(3x+8\right)\) ⋮ \(\left(x-1\right)\)
\(\frac{3.\left(2x-1\right)}{4}-\frac{3x+1}{10}+1=\frac{2.\left(3x+2\right)}{5}\)
giúp với!!!
các bn giúp mk nha nhân tiện kb lun
Tìm x
a) \(\left(2x-1\right)^6=\left(2x-1\right)^8\)
b) \(\left(3x+1\right)^8=\left(3x+1\right)^{10}\)
Tìm x thuộc N biết:
a, \(\left(x-9\right)^4=\left(x-9\right)^7\)
b, \(\left(3x-15\right)^{10}=\left(3x-15\right)^{15}\)
c, \(\left(x-8\right)^3=\left(x-8\right)^6\)
\(8^{2x+1}=2^{27}:4^6\)
\(x^{10}=x\)
\(\left(3x-1\right)^3=25\left(3x-1\right)\)
Tìm x :
\(a,x.\left(5x+10\right)+5.\left(x23+30\right)-9.\left(3x+5\right)=100\)
\(b,10.\left(8x+9x\right)+8.\left(2x-1\right)-2.\left(5-6x\right)=20\)
\(c,\left(x.5^2\right).\left(194+x.20\right)=50\)
Tìm x thuộc N
\(a,\left(x-9\right)^4=\left(x-9\right)^7\)
\(b,\left(3x-15\right)^{10}=\left(3x-15\right)^{15}\)
\(c,\left(x-8\right)^3=\left(x-8\right)^6\)
câu nò đúng mik sẽ cho 5 tick nhé
Tính x thuộc N
\(a,\left(x-9\right)^4=\left(x-9\right)^7\)
\(b,\left(3x-15\right)^{10}=\left(3x-15\right)^{15}\)
\(c,\left(x-8\right)^3=\left(x-8\right)^6\)
cho mik bài giải nhé đừng cho mỗi đáp án thế khó làm lắm
Tìm x, biết: \(\frac{-1}{2}.\left(3x+5\right)-\frac{2}{9}.\left(9-6x\right)=\frac{3}{5}.\left(x-10\right)-3\)
\(\left(3x-1\right)^3=25.\left(3x-1\right)\)
\(\left(3x-14\right)^3=2^5.5^2+200\)
