Answer:

The given such number is 6.

Step-by-step explanation:

Let the given such number  = m

Now, according to the question, the given expression is:

[tex]\frac{(m^{12}) }{(m^{9}) }   =  216[/tex]

By the LAW OF EXPONENTS:

[tex]\frac{x^a}{x^b}  = x^{(a-b)}[/tex]

⇒Here [tex]\frac{m^{12}}{m^9}  = m^{(12-9)}  = m^{(3)}[/tex]

or, the given expression becomes [tex]m^3 =  216\\\implies m = \sqrt[3]{216}  = 6[/tex]

or, m  = 6

Hence, the given such number is 6.
