Answer 2

Answer:

For this expression:

             a=15  , b=7 and c=4

Step-by-step explanation:

We are asked to find the value of a,b and c by representing the given expression:

$\sqrt[4]{15^7}$ in the form of:  $a^{\dfrac{b}{c}}$

where a is the base and b is the numerator of the exponent and c is the denominator of the exponent.

We know that the expression of the type:

$\sqrt[n]{x}$ is also written as:

$x^{\dfrac{1}{n}}$

Hence, we get our expression as:

$\sqrt[4]{15^7}=(15^7)^{\dfrac{1}{4}}\\ \\\\i.e.\\\\\\\sqrt[4]{15^7}=(15)^{\dfrac{7}{4}}$

         Hence, we have:

      a=15, b=7 and c=4
