2 mũ 3 phần 3 mũ 4 nha tk mình nhé

Cách viết khác : \(\frac{16}{81}=\frac{2^4}{3^4}=\left(\frac{2}{3}\right)^4\)

Chúc bạn học tốt ^^

\(\left(\frac{16}{81}\right)=\left(\frac{2}{3}\right)^4\)

\(\frac{16}{81}=\left(\frac{-4}{-9}\right)^2=\left(\frac{2^2}{3^2}\right)^2=\left(\frac{\left(-2\right)^4}{\left(-3\right)^4}\right)=...\)

\(\left(\frac{4}{9}\right)^2nha\)

4/9 mét vuông

(2/3)⁴ nha bạn

 \(\frac{16}{81}\)\(=\)\(\left(\frac{4}{9}\right)^2\)\(=\)\(\left(\frac{-4}{9}\right)^2\)\(=\)\(\left(\frac{2}{3}\right)^4\)\(=\)\(\left(\frac{-2}{3}\right)^4\)

\(\dfrac{16}{81}=\left(\dfrac{2}{3}\right)^4\)

\(\dfrac{16}{81}=\left(-\dfrac{4}{9}\right)^2\)

\(\dfrac{16}{81}=\left(\dfrac{2}{3}\right)^4\)

0,25 = (0,5)²

\(\dfrac{1}{49}\) = (\(\dfrac{1}{7}\))²

- \(\dfrac{27}{125}\) = (- \(\dfrac{3}{5}\))³

 \(\dfrac{81}{16}\) = ( \(\dfrac{9}{4}\))²

\(\dfrac{169}{196}\) = (\(\dfrac{13}{14}\))²

\(\frac{16}{81}=\frac{2^4}{3^4}=\left(\frac{2}{3}\right)^4\)

\(\frac{25}{9}=\left(\frac{5}{3}\right)^2\)

\(\frac{16}{81}=\frac{4^2}{9^2}=\left(\frac{4}{9}\right)^2\)

(2/3)⁴ = 16/81

\(\frac{16}{81}=\left(\frac{-4}{9}\right)^2=\left(\frac{4^2}{3^2}\right)=\left(\frac{\left(-4\right)^2}{\left(-3\right)^2}\right)=....\)

\(\frac{16}{81}=\left(\frac{4}{9}\right)^2\)
