\(x=\left(42-4,2.10+76.7,6\right):\left(0,01.0,1\right)\)
\(y=\left(689,7+0,3\right):\left(7,4:0,2-2,2-1,5\right)\)
\(Ta\) \(có:\)
\(x=\left(42-4,2.10+76.7,6\right):\left(0,01.0,1\right)\)
\(x=\left(42-42+76.7,6\right):\left(0,01.0,1\right)\)
\(x=\left(0+76.7,6\right):\left(0,01.0,1\right)\)
\(x=\left(577,6\right):\left(0,001\right)\)
\(x=577600\)
\(y=\left(689,7+0,3\right):\left(7,4:0,2-2,2-1,5\right)\)
\(y=\left(689,7+0,3\right):\left(37-3,7\right)\)
\(y=\left(690\right):\left(33,3\right)\)
\(y=20,\overline{720}\)
*** So sánh :
Vì \(577600>20,\overline{720}\) nên \(x>y\)
Hay \(x=\left(42-4,2.10+76.7,6\right):\left(0,01.0,1\right)\) \(>\) \(y=\left(689,7+0,3\right):\left(7,4:0,2-2,2-1,5\right)\)
