Answer:
4[tex]\sqrt{450}[/tex] = 4[tex]\sqrt{25 * 18}[/tex]
= 4 × 5 [tex]\sqrt{18}[/tex]
= 20 [tex]\sqrt{18}[/tex]
= 20 [tex]\sqrt{9 * 2}[/tex]
= 20 × 3 [tex]\sqrt{2}[/tex]
= 60 [tex]\sqrt{2}[/tex]
-5 [tex]\sqrt{0.6}[/tex] = -5 [tex]\sqrt{0.6}[/tex]
= - [tex]\sqrt{25 * 0.6}[/tex]
= - [tex]\sqrt{25 * \frac{3}{5}[/tex]
= - [tex]\sqrt{15}[/tex]
