\(3^3.1^8-3^3.15\)
\(=3^3\left(1-15\right)\)
\(=27.\left(-14\right)\)
\(=-378\)
Trl :
33 .18 - 33.15
= 27.1 - 27.15
= 27( 1 - 15 )
= 27.( -14 )
= - 378
Lm vội :)
Sai bỏ qa
33 .18 - 33.15
= 27.1 - 27.15
= 27( 1 - 15 )
= 27.( -14 )
= - 378
3^3.1^8-3^3.15
= 3^3 . ( 1^8 - 15 )
= 3^3 . ( 1 - 15 )
= 9 . (-14)
= - 126
