1) Viết các số sau dưới dạng lũy thừa
a) \(625=5^4\)
b) \(\frac{4}{9}=\left(\frac{2}{3}\right)^2\)
c) \(0,81=0,9^2\)
d) \(\frac{9}{64}=\left(\frac{3}{8}\right)^2\)
\(625=5^4\)
\(\frac{4}{9}=\left(\frac{2}{3}\right)^2\)
\(0,81=\left(0,9\right)^2\)
\(\frac{9}{64}=\left(\frac{3}{8}\right)^2\)
a)\(625=5^4\)
b)\(\frac{4}{9}=\left(\frac{2}{3}\right)^2\)
c)\(0,81=0,9^2\)
d)\(\frac{9}{64}=\left(\frac{3}{8}\right)^2\)
\(a)625=5^4\)
\(b)\frac{4}{9}=\left(\frac{2}{3}\right)^2\)
\(c)0,81=0,9^2\)
\(d)\frac{9}{64}=\left(\frac{3}{8}\right)^2\)
