0,36 x 550 + 0,18 x 126 x 2 + 3 x 324 x 0,12
= 0,36 x 550 + 0,18 x 2 x 126 + 3 x 0,12 x 324
= 0,36 x 550 + 0,36 x 126 + 0,36 x 324
= 0,36 x ( 550 + 126 + 324 )
= 0,36 x 1000
= 360
Ta có : 0,36 x 550 + 0,18 x 126 x 2 + 3 x 324 x 0,12
= 0,36 x 550 + 0,36 x 126 + 0,36 x 324
= 0,36 x ( 550 + 126 + 324 )
= 0,36 x 950
= 162

đúng chưa ?
tích đi
ko tích mét mẹ đó :)))
0,36 * 550 + 0,18 * 126 * 2 + 3 * 324 * 0,12
= 0,36 * 550 + ( 0,18 * 2 ) * 126 + ( 3 * 0,12 ) * 324
= 0,36 * 550 + 0,36 * 126 + 0,36 * 324
= 0,36 x ( 550 + 126 + 324 )
= 0,36 x 1000
= 360
0,36 x 0,50 + 0,18 x 726 x 2 + 3 x 324 x 0,12

\(1) 420+65.4=(x+175):5+30\)
\(\implies 420+260=(x+175):5+30\)
\(\implies 680=(x+175):5+30\)
\(\implies 650=(x+175):5\)
\(\implies 650.5-175=x\)
\(\implies 3075=x\)
\(2)x-4867=(175.2050.70):25+23\)
\(\implies x-4867=1004500+23\)
\(\implies x-4867=1004523\)
\(\implies x=1009390\)
\(3) 134-[(96-7x):4-2]=126\)
\(\implies (96-7x):4-2=8\)
\(\implies(96-7x):4=10\)
\(\implies 96-7x=40\)
\(\implies 7x=56\)
\(\implies x=8\)
\(4) 4-\{100-[(100-5x):8-5]:10\}:25=0\)
\(\implies 4-\{100-[(100-5x):8-5]:10\}=0\)
\(\implies 100-[(100-5x):8-5]:10=4\)
\(\implies 100-[(100-5x):8-5]=40\)
\(\implies (100-5x):8-5=60\)
\(\implies (100-5x):8=65\)
\(\implies 100-5x=520\)
\(\implies 5x=-420\)
\(\implies x=-84\)
