Please help me with this math problem so that I can figure it out so that I can do the rest of them on my own

Ok, so
We want to write:
[tex]8\cdot10^8[/tex]in standard notation.
Remember that, the exponent of the ten's base, is the number of times that we will write zeros. So, we're going to write eight zeros next to the number eight.
Then,
[tex]8\cdot10^8=800,000,000[/tex]And the correct answer is the blue one.
