Question

1,Tính nhanh

(m : 1 - m x 1) : (m x 2005 + m + 1)

Làm nhanh giúp mình nha!

Answer 1

( m : 1 - m . 1 ) : ( m . 2005 + m + 1 )

= ( m - m ) : ( m . 2005 + m + 1 )

= 0 : ( m . 2005 + m + 1 )

= 0

Answer 2

       \(\left(m:1-m\times1\right):\left(m\times2005+m+1\right)\)

\(=\left(m\times\frac{1}{1}-m\times1\right):\left(m\times2006+1\right)\)

\(=\left(m\times1-m\times1\right):\left(m\times2006+1\right)\)

\(=0:\left(m\times2006+1\right)\)

\(=0\)

Answer 3

(m : 1 - m x 1) : (m x 2005 + m + 1)

= (m - m x 1) : (m x 2005 + m + 1)

= (m - m) : (m x 2005 + m + 1)

= 0 : (m x 2005 + m + 1)

= 0

Answer 4

( m : 1 - m x 1 ) : ( m x 2005 + m + 1 )

= ( m - m ) : ( m . 2005 + m + 1 )

= 0 : ( m . 2005 + m + 1 )

= 0
