Answer:
No. It is not an Exponential Equation.
Step-by-step explanation:
Given[tex]x^{4} =15[/tex]
By the Definition of Exponential Equation which states.
"The equation is said to be an exponential equation when it has a variable occurred in the exponent and which have the same base."
For Example:
All given below are said to be exponential equations.
[tex]5^{x} =5^{2} \\7^{x}=49\\[/tex]
which can be rewritten as
[tex]7^{x}=7^{2}[/tex]
Now in the given equation [tex]x^{4}=15[/tex] it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation
