Answer:
a = 15
b = 7
c = 4
Step-by-step explanation:
Given in the question an expression [tex]\sqrt[4]{15}^{7}[/tex]
This expression can be written as [tex]15^{\frac{7}{4} }[/tex]
As we know that roots are most often written using a radical sign, like this, [tex]\sqrt[n]{x}[/tex] But there is another way to represent the taking of a root.
You can use rational exponents instead of a radical. A rational exponent is an exponent that is a fraction. For example, [tex]\sqrt[n]{x}[/tex] can be written as [tex]x^{\frac{1}{n} }[/tex]
Secondly two powers having same base can be multiply
[tex]x^{n}(^{m})=x^{nm}[/tex]
