Answer:

Step-by-step explanation:

You don't really need to do a permutation here. We know that there are 4 options for digits and three places so therefore we have 4 choices for the first digit, 3 for the second and 2 for the last so the answer is 4 * 3 * 2 = 24.

<h2>The required 'option C) 144' is correct.</h2>

Step-by-step explanation:

We have,

$(x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12$

To find, the possible value of x = ?

∴ $(x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12$

⇒ $x^{\dfrac{1}{8}+\dfrac{3}{8}}=12$

Using the exponential identity,

$a^{m} a^{n} =a^{m+n}$

⇒ $x^{\dfrac{1+3}{8}}=12$

⇒ $x^{\dfrac{4}{8}}=12$

⇒ $x^{\dfrac{1}{2}}=12$

Squaring both sides, we get

$(x^{\dfrac{1}{2}})^2=(12)^2$

⇒ $x^{{\dfrac{1}{2}}\times2}=144$

⇒ x = 144

∴ The possible value of x = 144

Thus, the required 'option C) 144' is correct.
