Question

2+ ½ - 4/3  +( -1/3 ) ^4

trả lời giúp mình với 

 

Answer 1

\(2+\dfrac{1}{2}-\dfrac{4}{3}+\left(-\dfrac{1}{3}\right)^4\)

=\(2+\dfrac{1}{2}-\dfrac{4}{3}+\dfrac{1}{81}\)

=\(\dfrac{5}{2}-\dfrac{4}{3}+\dfrac{1}{81}\)

=\(\dfrac{7}{6}+\dfrac{1}{81}\)

=\(\dfrac{191}{162}\)

 

 

Answer 2

\(2+\dfrac{1}{2}-\dfrac{4}{3}+\left(-\dfrac{1}{3}\right)^4\)

\(=\dfrac{5}{2}-\dfrac{4}{3}+\dfrac{1}{81}\)

\(=\dfrac{5}{2}-\dfrac{108}{81}+\dfrac{1}{81}\)

\(=\dfrac{5}{2}-\dfrac{107}{81}\)

\(=\dfrac{405}{162}-\dfrac{214}{162}=\dfrac{191}{162}\)
