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.

Answer:
20000000
Step-by-step explanation:
Finding factors is kind of a guessing game, if you have choices to pick from you can divide the number by the possible factor and if it turns out to be a whole number then that possible factor is a factor. let me show you
46/3=15.3 so three is not the answer
46/2=23 so, 2 is a factor
the possible answers you have look weird, i am not sure what 7B.3, 13c.2, or 23D.3 means but I hope I helped
