29 – [16 + 3.(51 – 49)]
= 29 - [16 + 3. 2]
= 29 - [16 + 6]
= 29 - 22
= 7
29/19.49/51+29/19.34/51-29/19.32/51
=29/19.(49/51+34/51-32/51)
=29/19.1
=29/19
\(\dfrac{29}{19}.\dfrac{49}{51}+\dfrac{29}{19}.\dfrac{34}{51}-\dfrac{29}{19}.\dfrac{32}{51}\)
\(=\dfrac{29}{19}.\left(\dfrac{49}{51}+\dfrac{34}{51}-\dfrac{32}{51}\right)\)
\(=\dfrac{29}{19}.1\)
\(=\dfrac{29}{19}\)

k nhé mình nhanh nhất
\(29-\left[4^2+3.\left(51-49\right)\right]\\ =29-\left(16+3.2\right)\\ =29-\left(16+6\right)\\ =29-22=7\)
29 - [42 + 3.(51 - 49)]
= 29 - [16 + 3.2]
= 29 - [16 + 6]
= 29 - 22
= 7
