For this expression:
a=15 , b=7 and c=4
We are asked to find the value of a,b and c by representing the given expression:
[tex]\sqrt[4]{15^7}[/tex] in the form of: [tex]a^{\dfrac{b}{c}}[/tex]
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:
[tex]\sqrt[n]{x}[/tex] is also written as:
[tex]x^{\dfrac{1}{n}}[/tex]
Hence, we get our expression as:
[tex]\sqrt[4]{15^7}=(15^7)^{\dfrac{1}{4}}\\ \\\\i.e.\\\\\\\sqrt[4]{15^7}=(15)^{\dfrac{7}{4}}[/tex]
Hence, we have:
a=15, b=7 and c=4
