\(160-(2^3\cdot5^2-6\cdot25)\)
\(=160-(8\cdot25-6\cdot25)\)
\(=160-\left[(8-6)\cdot25\right]\)
\(=160-2\cdot25=160-50=110\)
\(160-\left(2^3.5^2-6.25\right)\)
\(=160-\left(8.25-6.25\right)\)
\(=160-\left[25.\left(8-6\right)\right]\)
\(=160-\left(25.2\right)\)
\(=160-50\)
\(=110\)
CHÚC BẠN HỌC TỐT!
\(160-\left(2^3.5^2\right)-\left(6.25\right)\)\(=160-\left(8.25-6.25\right)\)
\(=160-\left[\left(8-6\right).25\right]\)
\(=160-2.25\)
\(=160-50\)
\(=110\)
160 - ( 23 . 52 - 6 . 25 )
= 160 - ( 8 . 25 - 6. 25 )
= 160 - [ 25 . ( 8 - 6 ) ]
= 160 - 25 . 2
= 160 - 50
= 110
cach lam la:
160-(8.25-6.25
=160-25.(8-6)
=160-25×2
=160-50
=110
k cho mk nha
