Question

We know that x=y is an single powerd equation.

But watch this,

x=y or, x/y=1 or, x.y^(-1)=1 or, x^1.y^(-1)=1

therefore, it is a 0 powerd equation [1+(-1) = 0]

So, the same equation is a 0 and a single powerd equation together. How can it be possible?

Answer 1

Dear student,
When we use the term powerd equation, we refer the power of a single variable.

In the above example, there was 2 variables, x and y.

To find the power of a equation, you cannot simply add the power of different variables.
That is a wrong method.

Here both variables x and y has single power.
