Question

tính nhanh:(2+4+6+.......+100) (36 x 333 -108 X 111 )

mọi người giúp mình với

Answer 1

\(\left(2+4+6+...+100\right)\left(36.333-108.111\right)=\left(2+4+6+...+100\right).\left[111\left(36.3-108\right)\right]=\left(2+4+6+...+100\right).0=0\)

Answer 2

(2+4+6+.......+100) (36 x 333 -108 X 111 )
=2x(1+2+3+......+50)[36x111(1x3-3x1)
=2x(1+2+3+......+50)(36x111x0)
=2x(1+2+3+......+50)x0
=0

Answer 3

   ( 2 + 4 + 6 + ....... + 100 ) ( 36 x 333 - 108 X 111 )
= 2 x ( 1 + 2 + 3 + ...... + 50 ) [36 x 111 ( 1 x 3 - 3 x 1 )
= 2 x ( 1 + 2 + 3 + ...... + 50 ) ( 36 x 111 x 0 )
= 2 x ( 1 + 2 + 3 + ...... + 50 ) x 0
= 0

Answer 4

(2+4+6+.......+100) (36 x 333 -108 × 111 )
=2×(1+2+3+......+50)[36×111(1×3-3×1)
=2×(1+2+3+......+50)(36×111×0)
=2×(1+2+3+......+50)×0
=0

Chúc bạn học tốt nhé!!

Answer 5

\(\left(2+4+6+...+100\right)\cdot\left(36\cdot333-108\cdot111\right)\)

\(=\left(2+4+6+...+100\right)\cdot\left[36\cdot111\left(3-3\right)\right]\)

=0
