\(27+73-30:\left(25-10\right)\)=\(27+73-30:15\)=\(27+73-2\)=\(100-2=98\)
d). 27+73-30:(25-10)
=100-30:15
=100-2
=98
chúc bn học tốt
\(27+73-30\div\left(25-10\right)\)
\(=27+73-30\div15\)
\(=27+73-2\)
\(=100-2\)
\(=98\)
Hok tốt !!!!!!!!!!!!
d. 27 + 73 - 30 : ( 25 - 10 )
= 27 + 73 - 30 : 15
= 27+ 73 - 2
= 100 - 2
= 98
27 + 73 -30 : (25 - 10 )
=100 - 30 : 15
= 100 - 2
=98
