Help please, try to explain it in steps for me if u can't that's fine, ty!
Iteru [2.4K]

Answer:

B

Step-by-step explanation:

We are given that Expression One is:

2\cdot 10^x

And Expression Two is:

4\cdot 10^{x+y}

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:

4\cdot 10^{x+y}=20000(2\cdot 10^x)

We can divide both sides by four:

10^{x+y}=10000\cdot 10^x

Recall that:

x^a\cdot x^b=x^{a+b}

Therefore:

10^x\cdot 10^y=10000\cdot 10^x

Divide both sides by 10ˣ:

10^y=10000

Solve for <em>y: </em>

<em />\displaystyle y = \log_{10}10000 = 4<em />

Our answer is B.
