Question

Tính :

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

Answer 1

\(\left(-\dfrac{1}{2}\right)^0=1\)

\(\left(3\dfrac{1}{2}\right)^2=12\dfrac{1}{4}=\dfrac{49}{4}\)

\(\left(2,5\right)^3=15,625\)

\(\left(-1\dfrac{1}{4}\right)=2\dfrac{113}{256}=\dfrac{625}{256}\)

Answer 2

\(\left(-\dfrac{1}{2}\right)^0=1\)

\(\left(3\dfrac{1}{2}\right)^2=\left(\dfrac{7}{2}\right)^2=\dfrac{49}{4}\)

\(\left(2,5\right)^3=\dfrac{125}{8}=15,625\)

\(\left(-1\dfrac{1}{4}\right)^4=\left(\dfrac{-5}{4}\right)^4=\dfrac{625}{256}\)

Answer 3

= 1 ; = \(\dfrac{49}{2}\); = 15,625 ; = \(\dfrac{625}{256}\)
