Question

(\(\frac{12}{199}\)+\(\frac{23}{200}\)–\(\frac{34}{201}\))×(\(\frac{1}{2}\)–\(\frac{1}{3}\)–\(\frac{1}{6}\))

Answer 1

Hình như mik chưa tính nhưng vế sau là = 0 nên bnj ko cần tính vế trước đâu

Answer 2

( \(\frac{12}{199}\)+ \(\frac{23}{200}\)- \(\frac{34}{201}\)) x ( \(\frac{1}{2}\)- \(\frac{1}{3}\)- \(\frac{1}{6}\))

= ( \(\frac{12}{199}\)+ \(\frac{23}{200}\)- \(\frac{34}{201}\)) x ( \(\frac{3}{6}\)- \(\frac{2}{6}\)- \(\frac{1}{6}\))

=( \(\frac{12}{199}\) + \(\frac{23}{200}\) - \(\frac{34}{201}\)) x 0

= 0

Học tốt ^-^

Answer 3

\(\left(\frac{12}{199}+\frac{23}{200}-\frac{34}{201}\right)\times\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)

\(=\left(\frac{12}{199}+\frac{23}{200}-\frac{34}{201}\right)\times\left(\frac{1}{6}-\frac{1}{6}\right)\)

\(=\left(\frac{12}{199}+\frac{23}{200}-\frac{34}{201}\right)\times0\)

\(=0\)

_Chúc bạn học tốt_

Answer 4

Đặt A là (12/199+23/200-34/201)

(12/199+23/200-34/201)×(1/2-1/3-1/6)

= A x (3/6 - 2/6 - 1/6 )

= A  x (0/6)

= A x 0

= 0
