Tìm x :
x : 5² = $\frac{3}{5}$² : 3²
x : 5²= $\frac{3²}{5²}$ : 9
x : 25 = $\frac{9}{25}$ : 9
x : 25 = $\frac{9}{25}$ . $\frac{1}{9}$
x : 25 = $\frac{1}{25}$
x =$\frac{1}{25}$ . 25 =1
@ Chúc học tốt
x : 5^2 = 3/5^2 : 3^2
x : 5^2 = 3^2/5^2 : 9
x : 25 = 9/25 :9
x : 25 = 9/25 . 1/9
x : 25 = 1/25
x = 1/25 . 25
x = 1
