Question

tính :

(0,6)⁵ : (0,2)⁶

Answer 1

(0,6)⁵ : (0,2)⁶

= \(\left(\frac{3}{5}\right)^5:\left(\frac{1}{5}\right)^6\)

\(=\frac{3^5}{5^5}:\frac{1^6}{5^6}\)

\(=\frac{3^5}{5^5}.5^6=3^5.5=243.5=1215\)

Answer 2

(0,6)⁵ : (0,2)⁶ 

\(=\left(\frac{3}{5}\right)^5:\left(\frac{1}{5}\right)^6\)

\(=\frac{3^5}{5^5}:\frac{1^6}{5^6}\)

\(=\frac{3^5}{5^5}:\frac{1}{5^6}\)

\(=\frac{3^5}{5^5}.5^6=3^5.6=243.6=1458\)

Answer 3

Answer 4

\(\Leftrightarrow\left(\frac{3}{5}\right)^5:\left(\frac{1}{5}\right)^6\)

\(\Leftrightarrow\frac{243}{3125}\div\frac{1}{15625}\)

\(\Leftrightarrow\frac{3796875}{243}=15625\)

Answer 5

(0,6)⁵ : (0,2)⁶

^{= \(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}\)}

= \(\frac{\left(0,2\right)^5.3^5}{\left(0,2\right)^6.\left(0,2\right)}\)

= \(\frac{3^5}{0,2}\)

= \(\frac{243}{0,2}\)

= 1215
