Answer:

3

Step-by-step explanation:

Let the number be [tex]x[/tex]. Hence:

[tex]x^{8}[/tex] ÷ [tex]x^{5}[/tex] [tex]= 27[/tex]

[tex]x^{8-5} = 27[/tex] [Laws of Indices: [tex]a^{m}[/tex] ÷ [tex]a^{n}[/tex] = [tex]a^{m-n}[/tex]]

[tex]x^{3} = 27[/tex]

[tex]x = \sqrt[3]{27}[/tex]

[tex]x = 3[/tex]
