B
Step-by-step explanation:
We are given that Expression One is:

And Expression Two is:

We are given that the value of Expression Two is 20,000 times greater than the value of Expression One. And we want to find the value of <em>y.</em> In other words:

We can divide both sides by four:

Recall that:

Therefore:

Divide both sides by 10ˣ:

Solve for <em>y: </em>
