Đơn giản hóa (\(\dfrac{1}{2}\))\(\dfrac{-1}{4}\)
A. -16 B. -\(\sqrt{2}\) C. -\(\dfrac{1}{16}\) D.\(\dfrac{1}{256}\) E.\(\sqrt{2}\)
Đơn giản hoá \(\left(\dfrac{1}{2}\right)^{\dfrac{-1}{4}}\)
A) -16 B) -\(\sqrt{2}\) C) -\(\dfrac{1}{16}\) D) -\(\dfrac{1}{256}\) E) \(\sqrt{2}\)
a,\(\frac{-6}{21}.\frac{3}{2}\)
b,\(\left\{-3\right\}.\left\{\frac{-7}{12}\right\}\)
c,\(\left\{\frac{11}{12}:\frac{33}{16}\right\}.\frac{3}{5}\)
d,\(\sqrt{\left\{-7\right\}^2}+\sqrt{\frac{2}{16}}-\frac{3}{2}\)
e,\(\frac{1}{2}.\sqrt{100}-\sqrt{\frac{1}{16}}+\left\{\frac{1}{3}\right\}^0\)
cho các số : 3 ; \(\sqrt{2}\) ; 16 ; -19 ; (-5\(^2\)) ; \(\dfrac{1}{2}\) ; -\(\sqrt{12}\) ; 0,25 . tìm giá trị tuyệt đối của chúng
\(\sqrt{16}\) = ?
\(\sqrt{36}\)= ?
