X^4=15 <br> is an exponential equation?

miskamm [114]

Answer:

No. It is not an Exponential Equation.

Step-by-step explanation:

Given $x^{4} =15$

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.

$5^{x} =5^{2} \\7^{x}=49\\$

which can be rewritten as

$7^{x}=7^{2}$

Now in the given equation $x^{4}=15$ it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation
