( 1 + 3 + 5 + 7 + ..... + 2001).(135 135.137 - 135.137 137)

Nhanh tick kkk

Answer 1

\(\left(1+3+5+7+........+2001\right)\cdot\left(135135\cdot137-135\cdot137137\right)\)

\(=\left(1+3+5+..........+2001\right)\cdot\left(18513495-18513495\right)\)

\(=\left(1+3+5+7+....+2001\right)\cdot0\)

\(=0\)

Answer 2

( 1 + 3 + 5 + 7 + ..... + 2001).(135 135.137 - 135.137 137)

= ( 1 + 3 + 5 + 7 + ..... + 2001).( 135 x 1001 x 137 - 135 x 137 x 1001 )

= ( 1 + 3 + 5 + 7 + ..... + 2001). 0 

= 0

k mik nha

Answer 3

( 1 + 3 + 5 + 7 + ..... + 2001).(135 135.137 - 135.137 137)

=( 1 + 3 + 5 + 7 + ..... + 2001).( 135.1001.137 - 135.1001-137)

=( 1 + 3 + 5 + 7 + ..... + 2001). 0

= 0

Answer 4

\(\left(1+3+5+7+...+2001\right)\left(135135.137-135.137137\right)\)

\(=\left(1+3+5+7+...+2001\right)\left(135.1001.137-135.137.1001\right)\)

\(=\left(1+3+5+7+...+2001\right)0\)

\(=0\)

Ta có:

\(\left(1+3+5+7+...+2001\right).\left(135135.137-135.137137\right)\)

\(=\left(1+3+5+7+...+2001\right).\left(18513495-18513495\right)\)

\(=\left(1+3+5+7+...+2001\right).0\)

Chúc bạn học tốt !!!

Answer 8

(1+3+5+7+...+2001)x(135135x137-137137x135)

=[(2001-1):2+1x2001]x(18513495-18513495)

=2003001x0=0

Answer 9

cách 2

(1+3+5+7+...+2001)x(135135x137-137137x135)

=(1+3+5+7+...+2001)x(18513495-18513495)

=(1+3+5+7+...+2001)x0=0
