chúc bạn hc tốt!!!
24 × 2 + 3 × 24 = 24 × (2 + 3) = 24 × 5 = 120
4 × 20 + 4 × 5 = 4 × 20 + 20= 4 × 20 + 20 × 1 = 20 × (4 + 1) = 20 × 5 = 100

mk là ARMY này
hok tốt
kt

\(24\times2+3\times24\)
\(=24\times\left(2+3\right)\)
\(=24\times5\)
\(=120\)
\(4\times20+4\times5\)
\(=4\times\left(20+5\right)\)
\(=4\times25\)
\(=100\)
a) \(24\times2+3\times24\)
\(=24\times\left(2+3\right)\)
\(=24\times5\)
\(=120\)
b) \(4\times20+4\times5\)
\(=4\times\left(20+5\right)\)
\(=4\times25\)
\(=100\)
\(24.2+3.24=24.\left(2+3\right)=24.5=120\)
\(4.20+4.5=4.\left(20+5\right)=4.25=100\)
Học tốt
