Question

Tìm |-79|; |10,7|; \(\left| {\sqrt {11} } \right|;\left| {\frac{{ - 5}}{9}} \right|\)

Answer 1

\(\left| { - 79} \right| = 79;{\rm{ }}\left| {10,7} \right| = 10,7;\)\(\left| {\sqrt {11} } \right| = \sqrt {11} ;\left| {\frac{{ - 5}}{9}} \right| = \frac{5}{9}\)

Answer 2

|-79|=79

|10,7|=10,7

\(\left|\sqrt{11}\right|=\sqrt{11};\left|-\dfrac{5}{9}\right|=\dfrac{5}{9}\)

Answer 3

Ta có: \(|-79|=79\)

\(\left|10,7\right|=10,7\)

\(|\sqrt{11}|=11\)

\(\left|\dfrac{-5}{9}\right|=\dfrac{5}{9}\)
