Question

Tính:
\(\left(\dfrac{-1}{3}\right)^2;\left(-2\dfrac{1}{4}\right)^3;\left(-0,2\right)^2;\left(-5,3\right)^0\)

Answer 1

\(\left(-5,3\right)^0\)\(=1\)

Answer 2

Answer 3

=\(\dfrac{1}{9}\);\(\dfrac{-801}{64}\);\(0,4\);1

Answer 4

\(\left(\dfrac{-1}{3}\right)^2=\dfrac{1}{9}\)

\(\left(-2\dfrac{1}{4}\right)^3=\left(-\dfrac{9}{4}\right)^3=-\dfrac{729}{64}\)

Answer 5

\(\left(-0,2\right)^2=0,04\)

\(\left(-5,3\right)^0=1\)
