\(303-3\cdot\left[655-\left(\dfrac{18}{2}+1\right)\cdot64+5\right]\)
\(=303-3\cdot\left(655+5-10\cdot64\right)\)
\(=303-3\cdot\left(660-640\right)\)
\(=303-3\cdot20\)
\(=303-60\)
\(=243\)
303 - 3.{[655 - (18 : 2 + 1) . 4³ + 5]} : 10⁰
= 303 - 3.(655 - 10.4³ + 5)
= 303 - 3.(655 - 640 + 5)
= 303 - 3.20
= 303 - 60
= 243
\(303-3.\left\{\left[655-\left(18:2+1\right).4^3+5\right]\right\}:10^0\)
\(=303-3.\left\{\left[655-\left(9+1\right).4^3+5\right]\right\}:10^0\)
\(=303-3.\left\{\left[655-10.64+5\right]\right\}:1\)
\(=303-3.\left\{\left[655-640+5\right]\right\}\)
\(=303-3.\left\{\left[15+5\right]\right\}\)
\(=303-3.20\)
\(=303-60=243\)
\(303-3:\left(655-10.64+5\right):10^0\)
\(=303-3:\left(655-640+5\right):1\)
\(=303-3:20\)
\(=\frac{6057}{20}\)
học tốt
303 - 3 : (665 - 640 + 5) : 1
303 - 3 : (25 + 5) : 1
303 - 3 : 30 : 1
303 - 0,1 : 1
303 - 0,1
302,9
\(428\times97+428\times2+428\)
\(=428\times\left(97+2+1\right)\)
\(=428\times100\)
\(=42800\)
\(995\times5+4\times5+5\)
\(=5\times\left(995+4+1\right)\)
\(=5\times1000\)
\(=5000\)
\(655\times6-355\times6\)
\(=6\times\left(655-355\right)\)
\(=6\times300\)
\(=1800\)
655 : 5 = 131
