_____________________________
[tex]\displaystyle \rm \dfrac{(0.6)^2 \times 0.5}{(0.2)^2 \times 0.45}[/tex]
→ Sederhanakan
[tex]\displaystyle \rm \dfrac{(0.6)^2 \times \cancel{0.5}}{(0.2)^2 \times \cancel{0.45}}[/tex]
[tex]\displaystyle \rm = \dfrac{\left(\dfrac{6}{10}\right)^2}{\left(\dfrac{2}{10}\right)^2 \times 0.9}[/tex]
[tex]\displaystyle \rm = \dfrac{\left(\dfrac{3}{5}\right)^2}{\left(\dfrac{1}{5}\right)^2 \times \dfrac{9}{10}}[/tex]
[tex]\displaystyle \rm = \dfrac{\dfrac{3^2}{5^2}}{\dfrac{1^2}{5^2} \times \dfrac{9}{10}}[/tex]
[tex]\displaystyle \rm = \dfrac{\dfrac{9}{25}}{\dfrac{1}{25} \times \dfrac{9}{10}}[/tex]
[tex]\displaystyle \rm = \dfrac{\dfrac{9}{25}}{\dfrac{9}{250}}[/tex]
[tex]\displaystyle \rm = \dfrac{9}{25} \div \dfrac{9}{250}[/tex]
[tex]\displaystyle \rm = \dfrac{9}{25} \times \dfrac{250}{9}[/tex]
[tex]\displaystyle \rm = \dfrac{\cancel{9} \times 250}{25 \times \cancel{9}}[/tex]
[tex]\displaystyle \rm = \dfrac{250}{25}[/tex]
[tex]\displaystyle \rm =10[/tex]
