Question

Tính:

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

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

\(\left(-\dfrac{1}{4}\right)^4=......\)

\(\left(-\dfrac{1}{2}\right)^5=......\)

Answer 1

(-1/2)^2=1/4

(-1/2)^3=-1/8

(-1/2)^4=1/16

(-1/2)^5=-1/32

Answer 2

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

\(\left(-\dfrac{1}{2}\right)^3=-\dfrac{1}{8}\)

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

\(\left(-\dfrac{1}{2}\right)^5=-\dfrac{1}{32}\)

Answer 3

( -\(\dfrac{1}{2}\))\(^3\) = -\(\dfrac{1}{8}\)

( -\(\dfrac{1}{2}\) )\(^5\) = -\(\dfrac{1}{32}\)
