tính nhanh 2004 . 37 + 2004 + 2 * 2004 + 2004 * 59 + 2004 / 324 * 321 - 201 * 324 - 324 * 101 - 18 * 324
\(\frac{2004.37+2004+2.2004+2004.59+2004}{324.321-201.324-101.324-18.324}\)
\(=\frac{2004.\left(37+1+2+59+1\right)}{324.\left(321-201-101-18\right)}\)
\(=\frac{2004.100}{324.1}\)
\(=\frac{200400}{324}\)
\(=\frac{16700}{27}\)

324 x 20 + 80 x 324 + 324 x 0

324 x 20 + 80 x 324 + 324 x 0

cho A + b = 12 tính 13 * a + 5 * b + 13 * b + 5 * a
b,a = 2004 * 37 + 2004 + 2 * 2004 + 2004 * 59 + 2004/ 324 * 321 - 2001 * 324 - 324 * 101 - 18 * 324
324+[112-(112+324)]
=324+(112-112-324)
=324+112-112-324
=0
324+[112-(112+324)]
= 324 + [112-112-324]
= 324 + [0-324]
= 324 + (-324)
= 0
324+[112-(112+324)]
\(324+\left[112-\left(112+324\right)\right]=324+\left(112-112-324\right)=324+112-112-324=0\)
