Hi there! The answer is x = 1
Let's solve this problem step by step!

First divide both sides of the equation by 8.

Now rewrite 100 as a power of 10.

Now we can use the following rule, which basically means that two different exponents of the same base must be the same

We now get this.

Finally divide both sides by 2.
