Tentukan hasil dari nilai mutlak berikut! a. |3-4-5+6| b. |2 1/2+1/3-7|

a.
|3 - 4 - 5 + 6|
= |(3 - 4) - 5 + 6|
= |-1 - 5 + 6|
= |(-1 - 5) + 6|
= |-6 + 6|
= |0|
= 0

b.
[tex]|2 \frac{1}{2} + \frac{1}{3} - 7|\\ =|2 \frac{3}{6} + \frac{2}{6} - 7|\\ =|2 \frac{5}{6} - 7|\\ =|2 \frac{5}{6} - 6 \frac{6}{6} |\\ =|- 4 \frac{1}{6} |\\ \bold{= 4 \frac{1}{6}} [/tex]

a.) |3 - 4 - 5 +6|
= |0|
= 0

b.) |2 1/2 + 1/3 - 7|
= |-25/6|
= 25/6
