Answer:
[tex]\sqrt9,\sqrt13} ,\sqrt21,\sqrt{109[/tex]
Step-by-step explanation:
Solve the following number :
-------------------------------------------------------------------------------------------------------------
[tex]\sqrt{9}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:9=3^2[/tex]
[tex]=\sqrt{3^2}[/tex]
[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]
[tex]\sqrt{3^2}=3[/tex]
[tex]\sqrt{9}=3[/tex]
-------------------------------------------------------------------------------------------------------------
[tex]\sqrt{13}[/tex]
[tex]\mathrm{Refine\:to\:a\:decimal\:form}[/tex]
[tex]=3.60555\dots[/tex]
-------------------------------------------------------------------------------------------------------------
[tex]\sqrt{21}[/tex]
[tex]\mathrm{Refine\:to\:a\:decimal\:form}[/tex]
[tex]=4.58257\dots[/tex]
-------------------------------------------------------------------------------------------------------------
[tex]\sqrt{109}[/tex]
[tex]\mathrm{Refine\:to\:a\:decimal\:form}[/tex]
[tex]=10.44030\dots[/tex]
------------------------------------------------------------------------------------------------------------
Hence the answer is
[Blue] [tex]\sqrt9,\sqrt13} ,\sqrt21,\sqrt{109[/tex]
------------------------------------------------------------------------------------------------------------
