Question

Tính nhanh :

  \(10^2+10^2+10+10+5\)

\(5\times10+10\times5\)

Answer 1

\(10^2+10^2+10+10+5\)

\(=100+100+10+10+5\)

\(=100\times2+10\times2+5\)

\(=200+20+5\)

\(=225\)

\(5\times10+10\times5\)

\(=\left(5+5\right)\times10\)

\(=10\times10\)

\(=100\)

Answer 2

10² + 10² + 10 + 10 + 5

= 100 + 100 + 10 + 10 + 5

= 225

5 . 10 + 10 . 5

= 10 . ( 5 + 5 )

= 10 . 10

= 100

Answer 3

10²+ 10²+ 10+10+5

=100+100+10+10+5

=200+10+10+5

=210+10+5

=220+5

=225

5x10+10x5

=50+50

=100

ai k mình mình k lại
