mk chi giup dc cau a thoi nha
1.53*82+8.2*1.53+10*1.53*22-1.53*86
=1.53(82+8.2+220-86)
=1.53*224.2
=343 026
a) 2,54901 - (1,54901 - 2009)
= 2,54901 - 1,54901 + 2009
= 54901 + 2009
= 56910
b) 1,53 x 82 +8,2 x1,53 + 10 x 1,53 x 22- 1,53 x 86
= 1,53 x 82 + 8,2 x1,53 + 220 x 1,53 - 1,53 x 86
= 1,53 x (82 + 8,2 + 220 - 86)
= 1,53 x 224.2
= 343.026
\(2,54901-\left(1,54901-2009\right)\)
\(=2,54901-1,54901+2009\)
\(=54901+2009\)
\(=56901\)
a) 2,54901 - (1,54901 - 2009)
= 2,54901 - 1,54901 + 2009
= 54901 + 2009
= 56910
b) 1,53 x 82 +8,2 x1,53 + 10 x 1,53 x 22- 1,53 x 86
= 1,53 x 82 + 8,2 x1,53 + 220 x 1,53 - 1,53 x 86
= 1,53 x (82 + 8,2 + 220 - 86)
= 1,53 x 224.2
= 343.026
